Actually Rumble IMHO the BenQ's laser goes out fairly quickly. If I were you I would just go for another Hitachi 79( I buy from here >
Hitachi 79. They're cheap and ship fast)
Seeing as how you bricked your current 79 you may want to go with a Hitachi 78 (
Link to buy Hitachi 78) since they are easier to flash as they don't require the 79 unlock CD.
Good Luck!
