I have a 2000 Specialized FSR A1 Comp for sale for $450 (will include new Front and Rear shifters and tune-up. I have not replaced the shifters yet, but will replace with comparable to existing rapid fire shifters). It has upgraded front suspension, handlebars, wheels and downhill style clipless pedals.
Here is a link to the bike's review:
