I really like the feel of the Colt 2000. Great grip. Is it the steel frame or polymer frame version? The main problem I know of is finding magazines, they are non-existant. If this one comes with at least 3 you are good to go.
The 2000 failed primarily because of timing. Shortly after introduction the Brady bill killed the high cap mags so the 14+ round 9mm's lost a lot of their appeal. If Colt still owned the patents, they could make some money on them, but they only had the patents for a short period of time and they reverted to Reed Knight of Knight's Armament.
In new condition with 3 mags, very fair price at $500 (IMHO)
