I've got a harbor freight basin on stand at the farm, and a 50 gallon stainless vat style at work.

The 50 gallon is heated (120*) but otherwise still just a recirc pump. It works great, but purchase price is around $1200 without the industrial solvent.

The HF isn't heated, but I run diesel in it and it cleans great. I've had diesel in it for 2 years and the pump still works fine. If you let your parts soak under the running solvent for 20-30 minutes then the brush will knock off the grime with no effort. It sits outside under a tarp, and still looks almost new.

If you get one, get one with the flexible nozzle as well as brush. Much easier to set it up and walk away than the brush only models.

For serious cleaning/rust removal, skip straight to muriatic acid. Not safe for aluminum though.
