I picked up a IO Magic at Circuit city with Mail in rebate that nets out to about $65. This is definitely the BEnQ 1620 as it is packaged in the smaller box and the specs match the BenQ as can be found in other threads. My son got one too so we have an extra one. If any wants it I am willing to sell it for what I paid. I live in the bay area in Northern California if you want to pick it up.
www.computergeeks.com has it for less than $60

Plus tax and Shipping? Still a good deal.
