I'd grab the floor model if they include the stand and replace the existing bulb. (New bulb, might as well say new set.) Highly doubtful you will find a new 70"XBR2 as there have been many others that have tried unsuccessfully. You are extremely fortunate to find this floor model. The Sony warranty should start with your purchase date so you're good to go there. Unless you just have to have the slim line XBR5, I'd grab that puppy. Of course, that's just my opinion. I don't ever buy anything off the floor, but considering the circumstances, I'd get it in a heartbeat, especially at that price!
