I had this projector in my house when i bought it. It is about 6yrs old and don't think anybody changed the bulbs (2).They are broken and need to be changed. I like it but it does make a lot of fan noise. Should i replace the bulbs and how much do they cost and where do i get them or is there a better projesctor out there that doesn't cost too much i.e less then $2,000? I appreciate all your help. Thanks, Mario
