For what it's worth--

Jenson has a Kalloy adjustable stem for $20 with free shipping through Monday:

It's ok as adjustables go, but they all suck, they tend to creak, and are very heavy because the mechanics that make it adjustable are made of steel.

I have one that I will probably keep on my errand bike. For my road bike I just ordered one of these:

I also have this: http://www.niagaracycle.com/product_...ucts_id=420632 It does the job but is heavy--but if your fork steerer has been chopped off, you don't have a lot of choice.

If ordering over the net, make sure you pay close attention to your handlebar clamp diameter--note that there is a difference between 25.4 and 26, for example.
