The 85/1.8 shown on my F2AS below cost only $130 shipped through evilBay. It did need to have its filter ring straightened a little, and has some engraving on it, but glass is nice, focusing is very smooth, and diaphragm works nicely. If you can find the H version with a factory AI ring (or even one that's been milled), go for it.
Thanks, I don't have any bodies which require an Ai or Ai'd lens, so I'll go for the older and perhaps less expensive version. One thing I will not buy is any lens with a bent or bent-and-straightened filter ring.
