I have a SIP lathe, I had it given to me. It wasn't working when I got it as the variable pully wheel was broken, probably by some one trying to get it off it's drive spindle. However I was able to get another pully, and soon had it up and running.This is the only lathe I have ever used so I'm not qualified to compare it with any other lathe, but so far it has done everything I have wanted to do on it. Maybe as I get more experienced and more ambitious, I might start looking for something better. It has its limitations on size of work piece, but as I said before, at the moment it's serving a perpose.
