Mathew-s,
I am in your place myself right now.
I have a 7x mini lathe and I want something with more capability. So, I am also considering something from PM.
What I am wanting, in addition to larger capacity, is the power cross-feed, the cam lock spindle, and a quick-change gearbox with adequate threading options in both inches and metric.
Other considerations for me are that it would be purchased along with complementary accessories. So the investment in this step-up is more than just the lathe. (accessories not necessarily all from the lathe vendor.)
One of my hangups is whether or not to get a stand from the lathe vendor or to build a suitable bench. (Maybe I'm getting too old to spend the time and money doing this: I can build EXACTLY what I want, but the cost in money may be more than the purchased piece and the cost in time will keep me away from other projects.)
Good Luck, and let us know what you decide.
