Yesterday, I posted in the under $3000 forum but received no response. Hopefully someone will chime in here. I need a new lamp for my Sharp Z15000 so i'm looking for some good advice. Naturally I would like a good price but i don't want to mess around with a knock-off bulb. This is my first time having to replace a lamp so i'm hoping you guys can steer me in the right direction. Looking at google, purelandsupply.com is selling them for $349, apexlamps.com for $369, provantage.com for $540, newegg for $492. Then there's ebay for $156 which i suspect is a knock-off. And Electrified has one for $95 through Amazon. After reading numerous reseller reviews, it's seems like a mine field out there. Any advice?
