First, let me say that I also own I7K, but six months ago for my Latitude C840 I opted for an external CD-RW drive; a wise decision in view of many problems reported on DellTalk for Dell's 24/10/24 drives.
The specifications for LSC-24081(M) look good, except that I don't understand why certain items (e.g., Mt. Rainier) are optional. Also the fact that the latest firmware is dated 2003-01-03 looks more encouraging than what Dell provides (e.g., for LG drives).
You should of course check whether LSC-24081(M) will fit in your bay; you could compare its dimensions to those given by Dell for your current DVD-ROM drive.
To get feedback from other users, I would advise you to post your question also on the Dell Community Forum

The fact that internal laptop CD-RW drives are sold mostly by OEMs is not suprising; apparently few customers are willing to risk other sources.
