I'm looking at a 2005 50DB. Looks like they only built the 50DB for one or two years (it replaced the 48DB and then was replaced by the 52DB in 2006 or 2007 I believe). Anyone have one of these? If so I'd love to hear pros/cons, things to look for, options that some had and some didn't, common failures, etc. Thanks in advance for an/all advice! Sincerely, Jason.
