I got one of the cheap-o stems from Tony at IRO. It's +/- 10 degrees. I'm going to try it out and if I like it I'll probably get a Thomson. The IRO one doesn't scream quality, but it gets the job done. I don't know how much more rise/drop you can get...that Deda Newton Pista has a lot of drop, but you have to run 31.8 bars.
