The DLP is not at the top of our list. We looked, but I found out the price to replace the bulb was $325.00 plus labor. With the TV costing only $1199.00, it just didn't factor for me.
We looked at a loaded Hitachi 50" plasma today that was pretty nice, and the price was right. With it having a 50,000 hour life, that figures out to something like 8 yrs., and by then the technology will have changed.
To bad you can't try them out in house before you buy.
