how much should I pay for used Cub cadet 2186?

[Scratchnbell]

It is a 44in 18 horse power with 120 hours. I believe it to be a 2001 model year. It comes with the 3 bagger grass catcher and aerator/fertilizer. The guy in the paper has it listed for $2250 OBO.
Is this a good mower and what is a good price for this unit?
Thanks
Bob
