George - I think this is more of a personal decision than anything else. I have the 2 hp Jet and decided on that size motor so that I could grow into the lathe - not out of it. I wanted the power - just in case - something in my future turning would require it - like coring bowls.

In my case, I chose the Jet over the Powermatic because I could not afford the Powermatic - but at least I could have the same size motor. Most everyone I have read that upgrades does it so they have more swing and additional power to handle the larger blanks. My biggest fear at the time was to buy a new lathe and then kick myself later for getting something underpowered.

I have heard numerous 1 1/2 hp Jet owners that are happy with their decision. I have not heard of anyone yet that was unhappy with their new 2 hp lathe because it had too much power.

Lots of luck with your decision! Looking forward to seeing your gloat - no matter which lathe!
