I'd Like to Start Shapeway... -ing...

I'm interested in making some 3-D printer-type stuff for custom work and was wondering what the go-to program was around here. I have a copy of Blender from a friend, but haven't tried it yet and was warned that it's pretty intense. Knowing that there are a lot of options out there for making 3-D models for printing, is there a specific program that's more user-friendly than any other, or better for a variety of models (I'd like to start with TF-style robot parts, like upgrade heads and weapons, but eventually move on to original figures, not necessarily of the action variety)?
Thanks,
