The last KHS mountain bike on sale at JensonUSA was a singlespeed and sold out quick. They now have the 2004 KHS XC204 full suspension model on sale for $650. The retail is $1000 so the savings is pretty good. Here are some specs:

The XC204 features a 7005 aluminum frame in a 4-bar linkage configuration for true cross-country performance. A Stratos rear coil shock delivers 3.5″ of travel, the perfect match to the Rockshox adjustable travel fork. With a great mix of Shimano®, Avid, Truvativ, and Kenda, the XC204 is sure to please.
