I'm trying to figure out how to get a good steel bike in my size. Used is cheaper. And I like building stuff - I find it relaxing and interesting. I'm thinking Reynolds 853 construction, just cuz I've been a Reynolds fan for a long time.

I could buy a frame with a 1" threaded headset, or one with the more modern 1-1/8. Is there much difference in performance between the two? What are the pros and cons? I'm pretty sure I can find a good fork for either size, with more choice for the bigger steer tube. Is there a huge difference?

I'll probably be building the bike up to be a 10 or 11 speed. Any thoughts appreciated.
