Solidworks is a good choice for the private user in general. Catia, IDEAS and ProE are very expensive.
Solidworks would be a great tool to get to know CAD as much of it will carryover to CATIA V5 etc...
I've had 5 years of CATIA V4 experience but now been a project manager for 2 years and miss the CAD work terribly.
Formula One teams use CATIA or IDEAS.
Renault, McLaren and Toyota = CATIA
Williams, Honda and Red Bull = IDEAS?
Good luck and send us a few screen shots of your work if you like.
