I was very lucky to have come into a little money a while back so I took advantage of the situation and ordered what I wanted rather than just getting a basic setup.
I got the 10" setup with the 2 Horse motor & variable speed controller. In addition to the supplied flat platen, I also got the small wheel attachment with 3 sizes (.5" .75" and 1.125" i think), the rotary platen (my favorite attachment!), enough tooling arms so that I have one for each attachment. I also got the base plate to make setup a breeze. The last thing I got was a tool tree so that I could keep things out of the way. I think that should keep me going a while. I'm very happy with my setup.
Rob was very helpful when I was trying to decide what to get. Give him a call and he'll set you on the right path.
Good luck!
Oh! One more thing. I live in a pretty humid climate so I try to combat rust any way I can. I took the time to paint what I could before setup to keep things from rusting.
That's my $.02
