DLP TV's question

I have been looking for a new TV. My 10 year old Pioneer Elite rear projection does not work well now in the 2-6 channels. If it is on long enough it gets better but it is slowly getting worse. I've had it worked on in the past but I think it is time for something newer. There are some vertical boards that could be taken out and re soldered but that is not easy with all the pins. Anything that could be reached has been re soldered. I like it because it changes channels in a split second. New digital TV's do not. I'm a channel surfer. So I'm thinking I'll try to find the best used DLP TV if they change channels fast. There may be some new old stock out there yet. Is this a viable option to find a new or newer non digital TV that changes channels fast? I may not be able to get hi def but I'm OK with that. I'm looking for a 60 inch. Has to fit in my custom made family room cabinet and the TV opening is 57 3/4" wide.

Thanks
