Way I figure it, it's worth just as much as you can get for it. But, you might want to consider trading it for something, that way you could even wind up with something worth more to you than the lathe. Awhile back I traded a flute I got for something like $25-30 for a very nice Delta scrollsaw, similar models of which are going for quite a bit more than $30. The guy was happy, he got a nice flute for a scrollsaw he didn't use, and I'm happy because I didn't have to spend $75-100, or more, for a quality used scrollsaw.

Some days, the supply of available curse words is insufficient to meet my demands.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
