I have two of the KDS Trinitron tube 17" monitors and they both work great. The newer one is the flat screen version. I believe both of mine came with 3 year warranties, and the touted "KARES" replacement system. Supposedly if your monitor goes bad, they overnight you a new one and you return your old one in the box the new one came in with prepaid freight. I haven't had the opportunity to test the warranty yet, since my monitors continue to work well in the year or two that I have been using them.
