Thank you.

Any Shimano 9sp mtn derailleur should work. Not sure what's available anymore, but you could go Deore, SLX, or XT. The "shadow" style derailleurs are real nice because they tuck in closer to the bike, out of the way, a definite plus on small-wheeled bikes. If you have the chain keeper bolted to the rear derailleur lower pulley, I assume you'll need to swap over the cage and hardware.
