Mooch, I might suggest checking out the soloist. If you're looking at the 1000 and 5000 then your pockets must not be shallow. The soloist is designed around 73-74 seat angle geometry and so it works well there. However, I just read a review of a person who put one up around 77 degree seat angle and got a little longer stem to ride it in a tri specific position and Loved it. Either way for $2000 you get a great road bike with all the things that make biking great even if you're not into triathlons( such as drop bars and integrated shifters). Plus, once a week you can flip your seat angle(to forward) and stem(to lower) and train like you're going to race, to me it is probably what I would consider if I could start from scratch with bikes, but I'm comfortable doing stuff like adjust stuff on my bike regularly.
Either way, don't go strait tri bike without doing a few first.
