Looks almost new. I think thats a good deal, especially with the 5 gallons of new solvent. I would pay $200, but I would still offer around $150 to see if I could get it a little cheaper.
No complaints on the one I used, but as others have said, it was leased with solvent replacement etc. From time to time with filthy parts the trap at the drain may need cleaning.
Im in uk got one of these it was a bit rusty fixed the supply pipe as it was leaking.made up s new light , some new cables and switch and after 5 years of it sitting out in the open she fired up .Good machines I paid £30 .
We have the safety kleen washers and solvent at work, looks identical to what you are asking about OP. They are decent parts washers and the solvent isn't too bad, either.
