RCA - 50" diagonal RCA Scenium DLP HD Television Review

The RCA 50" hdtv is the worst purchase I think I have made.  First the bulb explodes, but the bulb is not under warranty, then the color wheel burns out around $500 later the tv worked again, now the color wheel has burned out again 9 months after the the other one was installed.  I called RCA since its not under warranty (this all began when the warranty ran out)" they can't help me, I need to take it in and get it fixed" my question was will I have to buy a new wheel every 9 months? They can not guarantee parts.  I think I have a $2,000 paperweight. I feel like I pouring way to much money in this set, if I would have given up I could have bought a new lcd or plasma with the money that's in this one.  Terrible, terrible purchase by the time I get done I will have an extra $1100 in this set in repairs and they won't give me any guarantee it won't be more because "no one else has had problems with this tv"
