That is a choice only you can make...I prefer the experience of shifting myself and with very little practice you'd be fine with a stick, and enjoy it much more IMO! And the trannys are pretty much bulletproof.

 

I must agree about the 6 speed. Worst your going to do to it is destroy the clutch. Big deal call it a learning curve. Unless your just not a manual person. I've met plenty and the Tip tronic is fine but if you really want a Tiptronic please do your self a favor and get a Boxster S 07 or 08
