Question about DVDRW drives

[pat]

Are there any other options for a slim multi-burner (preferably DVD-RW) that will fit inside of my t42 instead of IBM's really-expensive version?

I asked the same question several days ago (too lazy to search for my post). It seems that the DVD drives that fit ultrabay slim (t42) are 9.5 mm
as opposed to the 12.5 mm drives that fit ultrabay 2000. I've seen quite a few 12.5 mm drives for sale (e.g. on newegg), but no 9.5 mm drives yet.
