CKM : Dude, what you wanna use the burner for? If you wanna burn ICE cd's, I recommend (heck.. IASCA seefus oso) TDK Burners. Cuz they are extremely stable and are capable of burning at 1x speed for best audio CDs.
If it's for everyday use, the Liteon is the one for you if you want a CD-writer. If DVD writer, go for the Pioneer as they are the best and are the pioneers in DVD writing technology. All others are copies. :P
Btw, there's this small hole thingy in your CDrom that'll fit a needle or paper clip. To open the CD tray if stuck, just stick in a needle into this hole and it'll release the tray. Also, in your case it may be worthwhile checking your IDE cable and get a contact cleaner to clean your IDE port as well as change your IDE cable. If it's only a eject problem or button prob, chances are it's not your writer. Unless you somehow managed to reverse the on/off switch polarity la.. which is impossible unless you DIY mod the thing..
