1" thick table
Owner says it is 220V 3 phase. Looks like 440V 3 phase on the name plate.
CL Bench Grinder Worth $150?

Yes, as long as you understand and meet the power requirements. The current owner may be running it on 220v, but IIRC it causes a 440v designed motor to run at ~1/4 the nameplate power and start up real slow, but on a grinder it shouldn't have that much startup torque to over come, just the interia of the wheels.

I'd pay that much for it. I mean, I'd try to haggle a little of course, but it looks like a pretty serious grinder that'll end all grinders.

Get the baldor buffer next to it as well.

cool looking grinder and if you have 3 phase it might take care of all the jobs you throw at it. I haven't seen a 2HP old grinder in that good of shape unless one of the GJ members restored theirs and showed it on the vintage grinder thread. check that thread out if you haven't already.
i agree to try and buy the Baldor buffer and that cast iron Baldor stand if you can. i'm guessing the baldor buffer might be a 3/4 HP so if it is and the cast iron stand is in great shape it retails for around $1000 for the stand and the buffer.

If you do get it, better bolt it down really well. That thing looks seriously top heavy....

I've got a grinder that size (12" wheels, 2HP) and really, unless you're doing a great deal of fairly heavy fabrication, no, it's not always worth it.
A grinder that size is a heavy starting load (due to the wheel inertia) for a VFD, and not recommended for a static converter. So unless you have native 3-phase, you'll need a rotary converter- and unless you keep it running most of the time, you'll find it's inconvenient to start the rotary, start the grinder, touch up a small part, then shut everything off.
I really only use mine for heavy work- either lots of parts or thick chunks that need a lot of metal removed. And while I do that kind of thing on occasion, it's getting kind of hard to justify the room it takes up.
That particular unit is also 440 volt. It can, sort of, run on 220V, but it'll be way down on power. You could get a transformer to turn your native or generated 220V 3-phase into 440, but that's just more complexity and cost.
If you do get it, you'll also find those tool rests are close to useless. They're nicely made and were probably perfect for whatever they were doing with it (probably deburring big chunks of plate) but for a day-to-day job shop or home shop, you'll find them getting in the way for 80% of what you need to grind.

Many VFD's can be programmed to ramp up the power at turn-on, so the in-rush current would be tolerable, but I don't see many that put out 440 vac with less than that for input voltage. Since this grinder appears to be 440 v only, I think you would be hard pressed to find a VFD that would power it off of single phase (120 or 240).
