At that price there is probably already a buyer lined up and 10 more hoping the first guy no shows. Email them anyway. Maybe you'll get lucky.

Well it's old, it likely (almost certainly) has Babbitt bearings in the quill.

As limited as it is without a Z axis down feed, I strongly doubt it has people lined up to buy it.

With only a drill chuck to hold the cutters, (or possibly use the old taper shank drill bits directly in the spindle) its not going to to come even close to tool room accuracy.

It IS an interesting piece, but it's more of a museum piece that a working tool due to it's limitations.

I think for what it is it's priced about right...

Amazingly they have a cult like following, almost like south bend stuff.

Is it worth $200, o yea. Just keep in mind it is nothing like a standard Bridgeport, barring the fact they both have knees. Other than that it looks very well tooled, which is what makes up most of the cost/value.

I've had this model for about 5 years. They are very fine small mills. This is a steal at $200. I paid $900 for mine but it came with a very nice Atlas milling vise. There are Timken tapered roller bearings in the head not Babbitt bearings. I've seen these go
for as little as $300 to $2000 on EBay. These were made by Benchmaster in Los Angeles from about the 1950's until the late 70's early 80's. Benchmaster also manufactures a very fine bench press. There is a Yahoo group on Benchmaster mills that is very good. Check it out.

Hm... that's an interesting deal. And in this case, "interesting" is used like the supposed old Chinese curse, "may you live in interesting times". :D

$200 is a good price, just in general. Won't break the bank too hard, and chances are you can get your money back later if you decide to resell.

However, the mill isn't exactly a steal. It's decent, and I'd rather have it than a micro-mill like a Taig or Unimat, but it's still a tiny, low-powered, bare-bones unit with more than a few shortcomings.

Assuming the spindle bearings aren't trashed, and the table ways are reasonably tight, you can do some useful work with it. But without a quill, drilling is a pain in the adz- and really, depending on what you're doing, drilling can be 1/3rd to a full half of the machining you need to do.

It's not a bad deal overall, but keep in mind it's very limited in what it can do.

It's also worht noting that that particular sale is boosted somewhat by the extras- there's three boxes of tooling, including tool holders, Morse-taper drills, what look like they might be Morse-taper reamers or cutters, a couple of fly cutters, and other goodies.

One box, though, appears to be nothing but square lathe tooling- useful if you have a lathe, of course, but apart from a few bits you might use in one of the fly cutters, won't do the mill any good.

That little motor in a box is, however, very curious. That's a tool-post grinder, with what appears to be both an OD and an extended ID spindle. It doesn't look like a Dumore, but it's got a nice fitted case, several shanks and accessories, and possibly some extra wheels. If you don't need it (I've been a machinist for 15 years and I've used one maybe four times) you can probably turn that on eBay and make the price of the mill back. (If you buy the mill, I might even be interested in the grinder.)

Last, that block next to the mill base might very well be a cast-iron surface plate. Very handy for setting up and layouts, assuming it hasn't gotten rusty and/or somebody hasn't cleaned it off with a wire wheel. :D

The little plate, too, could fetch a few bucks on the 'Bay- depending on condition, of course. Even rusty, though, somebody'd give you $40-$50 for it, just so they could practice scraping.

He's got a "project" South Bend lathe up for sale, too. Looks like a nice project, and would be much more useful if/when fixed up. :D

Doc.

Yes it is small, but looks like a bargain to me...
There is a bunch of stuff there to help you get going and it's small enoughnthat it would be easy to do a quick repaint and make it look really nice.
Someone should already own it for that amount.
Good machine to learn on and then resell later

To add to the pile, YES! I would buy that in a minute unless its got major issues/broken castings somewhere. Ive been through several of those, they are dead nutz simple, and at that price you can sell just the mill to triple your money fairly easily. Not saying its something I would enjoy using very much owning a Bport too, but a small basic mill is better than no mill, so go get it already.
