I have the cheap 20 gallon one and I love it. Mine is the "Tool Shop" brand from Menards, identical to the Harbor Freight one.

I use Castrol Super Clean for solvent. It is water based. It cuts grease as well or better than the organic solvents but without any smell, is nonflammable, and biodegradable. You have to wear gloves or it will eat up your hands. You have to be careful with aluminum parts - don't soak them for more than about half and hour, as the solvent will etch the metal and eventually eat it up. With 12 gallons of Super Clean I can get through two full knuckle jobs before it's got too much crap in it. It's more expensive than other parts solvent but you don't have to buy it very often.

I think Castrol sold this product and it's just called "Super Clean" now.


EDIT. I've had mine for three years. Three full knuckle jobs and some other stuff. Zero problems. The "filter" is just a piece of nylon mesh stuff, not very efficient.
