I won't talk you down because I've toyed with getting a DLP TV just to have a newer TV until the front projector technology I want matures. That's one of the models I've considered, though I haven't kept up on them lately.
Besides bulb replacement, it seems fan noise could be an issue with different models, but I don't know about that model in particular. I think that would get on my nerves if it contributed much audible noise, but I'll have the same issue when I go with front projection.
You should get one so I can live through you.
