i bought PLV Z60 in Dec 08. about 2 yrs now. approx 875 hrs on the lamp. i don't know if lamp has dimmed in last 2 yrs, but i am extremely satisfied with the pj so far. i am feeling the upgrade itch on pj. so my questions are..
1- if i upgrade, i plan to go for Epson 8100 or 8350 pjs. will i see a huge improvement over Z60 on watching bluray? worth spending 500 more?
1- going by my expected usage, i will hardly be at 1500 hrs in next one yr, i.e. after 3 yrs of usage. will anything else will be a problem in say another year? or will the picture quality degrade significantly?
2- i use the pj as per instructions, have it in a temp-controlled relatively dust-free room. is there anything more i can do to avoid picture degradation?
3- officedepot and staples etc sell dust-busters in a bottle. is it ok to use it from say 10" on my projector interior? or should not do that?
