Hi Mark,
I'll post more comments on the PM2014 after I've used it awhile but here are some initial thoughts:
How do you plan to use it? I thought that I would want to do small and medium sized items (maybe some spindles and end table legs), but nothing super long, meaning I ruled out full sized lathes.
Reasons I chose the 2014 were 1) versatility (just picked up the bed extension for longer items and for the ability to turn larger bowls off the end), 2. company reputation/quality of equipment build, and 3. it was priced at a point I could afford. I first looked at the Jet 1221VS which I believe to be a nice machine, but when I increased my budget, I felt that the PM2014 was a better long-term match. We'll see how that pans out, but so far very impressed with how solid this thing is. Nothing cheap about it imo).
I'm also putting together a makeshift mobility kit and can let you know how that works out, as well. GRJenson said above that he placed his on a livestock pen mat which really helped stabilize it. If mine moves too much with the mobility kit, I could see grabbing one of those mats as I've used them in other situations.
