I got one on Ebay.. and it works great.. i DL AVI movies and Watch it on my tv.. no more dvds... Mys support up to 500gb so i could put 600-700 movies in it.. If you want to get one.. get the one that has SD/MMC on it too... The new's one support up to 750G and has SD/MMC.. but it's $140 and $35 shiping..
tho u know u want the dodgy brands cos they can play all the dodgy copies =P but then u want a proper one, so its got better quality =)
