I have heard nothing but bad things about those machines....very old atleast 10 or 15 years old....id say its worth $500 at most and honestly I wouldnt even take it if it was given to me....IMO....whats your price range? there are a lot of good used machines out there now with the economy so bad you can find great deals but if i were you id pass on this one...
Jon Don in MLT has or had one for sale for $1500. A buddy of mine is selling his for $4000 in an astro van. TM engine had alot of money put into it and the van had new tranny, engine and other stuff.
I think this was the model that was supposed to compete with the Prochem Legend when they were popular. I think they are similar in blower size/heat etc. Not 100% sure though.
If it is in a Van and I had to take it out then I would charge $300 for it if it is already taken out I would give $300 for it.
Remember down time is COSTLY. It is not just the repair/parts cost but the time lost. A New(ish) machine is way cheaper to run then a used machine that needs constant attention no matter how little you pay for it. The price of a new machine is what 3-500 a month? Hell one day of lost time a month on that used machine and you could have bought a new machine. Just something to think about.
