Got a Pacific Digital 12X10X32 from Circuit City back in January. Only had to do a firmware update to support newer 32X and 40X media. Burns like a champ. Fully compatible with Clone CD all the way back to Version 2.8xxx of Clone CD. Would highly recommend their drives if on a budget. Cendyne's I hear can be a bit touchy. Same with the LG's--then again, a firmware update may be able to fix some of those issues as well. The LG's are now being put on the shelves in the local Wal-Marts. Got some good deals on a DVD read/CDR-RW combo drive for like $90 right now at our local SuperCenter in SC. Of course to future proof yourself, get a Pioneer A03/103 or A04/104 and snag a copy of PrimoDVD, CloneCD, and CDRWIN. You will (virtually) never fail, as far as I've seen on the forums.
Good Luck!
