I have to agree with NWG. I like the looks of that Kona (assuming it's your size), but I bought a used Titus Racer-X of the same vintage (2000) in 2008 or 2009, and even then, I had problems getting work done on it. I wanted to get the front fork rebuilt, but the shop couldn't do that due to parts availability with the fork company (Rockshox, I think), so I had to buy a new (used, actually) fork. I was able to get some other work done that it needed but all the drivetrain parts had to be ordered as they were already outdated and no longer available in the shop. It also had canti brakes, which were fine for me, since I only rode it in fair weather and easier trails. I loved that bike, but it was already outdated 8 years ago, so I don't know that I'd recommend this Kona, although the price is so cheap, I can't say not to do it -- once again, assuming it is your size -- but I wouldn't plan on doing a lot of upgrades to it.
Good luck!
