OK i'm a bit of a newbie here so i didn't know where to post this but i think this will do. I've seen gigablock DVD + R DL media selling on ebay for as little as .45 cents a piece. They DO make a point of listing a compatibility chart and they prefer LG models. These drives sell for as little as $25 but I would prefer an external drive. Can anyone tell me if any of these model #'s : GSA-H20L, GH20NS15, GSA-H62N, GSA-H55N, GSA-H42L, GSA-H42N, GSA-H22N, GH22NP20, would have the exact model in an external? Thank You VERY much i've had no luck with google any help would be appreciated p.s. at these prices it's worth it just to try, right?
