Buying questions - which plane?

Ok,

First time plane buyer, I've been looking for some time now.

I've narrowed it down to a few, looking for some big picture comments
pro/con on these:

Commanche 250 or 260
Commander 114
Mooney M20J
Socata TB20 Trinidad

Dont' care about purchase price right now, avionics, etc. Looking for
performance/maintenance/operating costs/issues people know of.

We will normally be loaded with myself, wife and son (400lbs) Plus weekend
bags (100lbs max).

My wife wants speed, speed, speed. I'm not as concerned about speed as I am
performance. I need short field performace as one of our primary fields is
a 2500' grass strip at 2000' DA. I'd also like to climb up into the teens
if needed to get over minor w/x.

Any advice would be appreciated.

tks.
