FWIW; Penn State Ind. has a Jet clone they sell under their name Turncrafter Pro. It sells for under $200 and is everybit as good as the Jet or Delta. The Vega mini dup will mount in the same manner.
I own the Jet variable speen mini. I have a vega dup on it. My bench is against the wall so I have to remove my dup when I want to turn manually. I have designed some fixtures that can be atached to the dup that will allow you to put it right back where it was so the changeover is very fast! I just need to make them
You can get a real nice lathe with a bed extension etc. for under $300.
Good luck.
