My beamer cost me about 90€(40€ for the overhead-projektor/ 40€ for a tft panel with brocken backlights) and a new lamp (400 W / 36 V) 16€.
I will never watch a film in on tv again- and i can`t understand how you can spend 4000€ for a new beamer and about 300€ for a new lamp if it is so quite simpel and cheap to do it by your self. :D -enjoy!
