pick a stem 32-40 bucks - http://www.universalcycles.com/shopp...?category=1728

this is a cheap-ass way to go, but if you remove the "ass" part, you're left with "cheap."

under $100 bucks, do the labor yourself, it's not that difficult. i'm sure you could find something online that will explain it fairly well. you're going to need some specialized tools, hope you know someone. any particular reason you want a quill instead of threadless? seems like a lot of work just for aesthetic value. because i'm pretty sure with a different stem with the right angle/length you could get something functionally similar.
