The rockshox line goes more or less like this

Judy / GPS: entry level forks, not for heavy riding. I wouldn't use one if I were planning on riding more than weekly.

Pilot, Duke, SID (in order of expense): RS' cross country forks. Never been on a pilot, couldn't say much about it. I suspect its pretty low quality. Dukes are nice and stiff, but I've heard people have trouble if they ride them hard. SID is the lightest XC fork commonly used. Its kind of wobbly, and costs a lot.


The only other forks are Psylo and Boxxer. Boxxer is meant for downlhill, while Psylo has models for Freeriding as well as XC. Both are out of your price range.
