well, since u've sold most of ur KM stuff, starting over shldn't be dat bad. rite? ;p
for all ur choices, IMO, stuff the 5D. if u really dying for FF DSLR, take the same amt of money and go get a 2nd-hand 1Ds. also FF and pro-body some more. more worth the money, IMO. a few of my canon-diehard colleagues have tried their hand at the 5D, and they came away unimpressed. question is u need speed or res. :think:
