I have a new KDS55A2000 SXRD 1080p that uses the XL-5200 lamp and I want to have a spare on hand, "just in case." Does anyone know where a one can buy at reasonable cost a QUALITY, RELIABLE replacement? Sony's price, $299, seems very high to me. Also has anyone heard if balasts in these SXRD (LcOS) sets go bad, and if so where can they be readily obtained? Any help will be sincerely appreciated. M
