Amy & Mimi - I am ahead of both of you but have gone through exactly what you are going through now. I started the process about a year ago when the physical pains I was having got too much to deal with any more. I had a bike fit & tried to make-do with my old beloved Lemond. By June I knew I needed to do something different so I, too, opted for a custom frame. Mine is from Independent Fabrication. I ordered it somewhere around July 1 and took delivery of it at the end of October....long wait but definitely worth it.
For those non-cycling friends who just don't understand - tell them this bike is your "little red sports car" or better yet, find something they are obscessed with and use that as an analogy. And ride and enjoy those new bikes!
