Search for completed sales on E-bay. I am not a hobby guy, my shop is equipped with industrial type equipment. I did sell off and then acquire quite a few items over the past 5 years. I did notice used industrial type equipment took a beating (I sold things in 2008 for 1/3 of what I paid it 2003). I checked E-bay, and Craigslist for pricing, and noticed some of the smaller items held their value better (like a hobby guy with limited space would want). I believe it is because things like Mini mills, and 6 x 12 lathes can be moved cheaply by anyone, and shipped for small amounts of money. Anyway, you could even search current E-bay listings, but some people ask too much as they don't realize what the recession did to used equipment prices. To sell E-bay is getting pricey with fees and I believe they charge $25 just to list something in the machinery section. I would just try a free Craigslist add to start, you can always keep lowering the price if you get no nibbles, make sure to post nice clear pictures, and include model# and year of manufacture. Another rule of thumb if something is fairly new and in good shape people will pay 50% of what a new one goes for. Just start googling the make and model #'s and you will get the information you need. As an example I just googled "microlux 7x14 mini lathe" Found they now only make a 16" for $795.00, your's is 2" smaller, so if in good shape I would list at $425 or best offer and probably take $350.00.
