tough one to answer, considering the 'mid-price' is probably dropping still. i mean my first projector was ENTRY level just 4(?) years ago and cost me 1500. about twice the price a similarly market placed projector would today.
there's so much going on in the flat screen market as well that could drastically change projector demand. death of plasma could make enthusiasts explore front projection to avoid LED backlighting. monstrously sized OLED/LED could bite into the entry level projector market. and that's just the stuff we already know about it
