Be prepared for sticker shock, but A Hutchins will be the last DA you ever have to buy. Especially if you are just a DIY guy. What are your intended uses. Hutchins makes sanders to be used all day everyday in body shops. I personally have a 4560. The 3500s are ok, but I do not like the muffler design. They are prone to breakage when dropped and when the muffler is broken they are loud as hell.

Hutchins is probably the best, but Chicago Pneumatic is pretty good too.
(not central pneumatic / aka harbor crap store junk)
I've got a National Detroit DA also & it works great.

I have a Craftsman I bought about ten years ago, the handle/actuator is tweaked but is still running. X2 on the Hutchins.

The Dynabrade is a good value. We have several at work and while they don't see the use that a body shop would give them, they get used and abused more than most DIYers would. They work well and need very little repair.

I have used Astro pneumatic, Snap On, IR, Dynabrade and Mirka. For the same orbit size, the Mirka seemed to cut the fastest, the Snap On and Dynabrade felt nicer and easier to control. I never cared for the IR or astro mostly because they have a less comfortable shape. Overall the Mirka and Dynabrade were my favorite.
In any case, i'd suggest getting a hook-and-loop pad, as it works well in a dusty bodyshop.

The older Dynabrade was 10,000 RPM. The new ones are 12,000 RPM.
Maybe that was the difference you saw in cutting speed?

Mine are Dynabrade. But I have a bunch of Mirka pads. Both are top shelf.

Hands down: www.hutchinsmfg.com

I have the DA & Straight line sander, they are powerful, good speed control, and move a load of filler.

High speed is not the secret to moving filler it is torque, speed just wears out the sand paper quicker.

I ran my sander at the highest speed when I did not know any better, then discovered dropping it enough to sand increased the life of the paper, and sanded.

Not a cheap tool but a very good tool, best of brand..

You've got to work on your technique.
A DA sander sands primarily on the orbit. The rotation is really there only to make the orbits more random so you don't end up with swirl marks. You need to vary your palm pressure to control the rotation speed. 100-200 RPM seems around right.

Whether orbiting faster helps it sand faster or just waste paper depends on a bunch of other factors. But in many cases, orbiting faster can indeed get you faster stock removal.

Absolutely true. I work in raw metal, using a da to blend in ground welds, hammer and other marks from hand forming. There's always a sweet spot in the speed range where you're working efficiently. Flat and curved surfaces are different as well. I rarely run the tool wide open.

There is a company called AirVantage tools www.airvantagetools.com that makes great sanders. They are ergonomic and perfectly balanced. It is my choice is your looking for quality and durability. It can be ordered for around $130.00 for standard non-vac with PSA or Velcro pad. You can order one from abrasive ideas 226-787-5405.

You can get a 3/16" orbit (for more agressive kick) or a 3/32" orbit kick which can give a tighter less agressive finish. I generally recommend that one for high grits ...

It sure does depend a lot on what you're doing. Certainly, if the whole pad is not in contact with the work surface (flattening raised areas, working over curved surfaces, etc), you will not be able to get the full power out of the machine.

Ive been using a Hutchins for 15 years now. You can't go wrong with a Hutchins it'll be the last one you buy. Not cheap but well worth your money.

Just one more vote for Hutchins. Not often is the best tool also made in USA.

Do not know what you are talking about, "Certainly, if the whole pad is not in contact" ?

The DA & Streight line sanders are used for blending, the sander will run at the power it is set at.

Makes no sense what you posted, sounds a if you have not had the pleasure of using a Hutchins.

I use a National Detroit DAQ 8-10 hours a day and they have been great. Maybe not quite as good as the Hutchins, but I felt it was the best bang for the buck. Cost around $150 or so.......

It operates at 45 to 60 psi and is very aggressive.....
