Oh I see. Budget is an issue for me (That's the only reason I'd be keeping the cranks and wheelset etc for the whole bike). But i feel like i could make a quality build up from a frame only. I have experience in taking apart bikes and putting them together. I got a bottom bracket remover and a friend who can install headsets so I'm not really worried about that.

My build right now if it was a FRAME only would be

A TT Frameset
A Sugino RD2 Crank + BB
Track drops (maybe a nitto but I'm getting greedy )
A whatever headset, stem and seatpost that look decently good
A basic wheelset as in something that is similar to the stock ones that come with the complete TT but maybe nicer hubs haha. (Anyone know where I could get a good set for around 100 or I might just buy someone's used BD wheelset)
Brooks saddle.

Knowing that I'm going to use those components, I don't want to waste my time buying the complete bike and having crap parts laying around. But The complete bike does come as a pretty good deal and does come with the whatever seatpost, stem and headset...

EDIT: Oh and time isn't really a factor. I have a different bike I converted from a road bike to a single speed so that's where i learned how to take the bike apart and put it all together. The only factor im concerned about is Budget vs. Quality. If quality increases, I'm not afraid to put in a little more. If budget increases, quality better increase. But things like the Truvativ Tauro vs the Sugino RD2 Crankset, I don't know if that'll really make a difference in functionality. I know its an upgrade in quality but will i really notice the difference?
