I am a proud owner of panasonic ax 200 fr more than 18 months.lamp has run more than 1100 hours!its still goin very strong.If u want flexibility n easy installation,no other proj comes close to the ax-200.HD videos n blu-ray r amazing,better than most theatre screens.i wont advice buyin a used one, unless lamp runtime is less.its very reliable,no probs till nw. the proj has seen 10 hrs continuous runnin, frequent powercuts,etc.til today nt a single prob.
cant comment on ur other options as am nt familiar with em
