tfreer,
You're not alone!
I've been through 5 engine choices (L28ET, SR20DET, 7M-GTE, RB25DET, and finally RB26DETT). I'm installing the RB26, but will be building an RB30 on the side (go figure!), Bought and sold 2 sets of wheels before settling on the CCW's, have 4 pints of different paint colors (not including the one I SAY I'm going to use), have an Q45 R200 VLSD and am thinking of going to a clutch type, have purchased 2 sets of fender flares before making my own, and I go back and forth on a weekly basis as to which EMS to use (current choice right now is the AEM).
