Projection fosho, not sure what your budget is but we got a 71"HD for $4k. Our old 55" projection lasted around 7-8 years until it got messed up, but it was a simple fix. After sitting for a bit it was good as new

edit: and we have the old Bose 5.1 (9ish years old), the bass on this thing is CRAZY. I can get the whole house shacking
