Our publishing company has an older iBook, "ice colored" 600mhz G3 with a CD-ROM drive for the optical drive. The CD-Drive doesn't want to stay "latched" inside like it's supposed to. It has a decent amount of RAM and hard drive storage and I'd like to easily install Tiger on it from DVD. So, I'm checking around some of the online places that sell replacement Combo drive compatible opticals for this iBook. My local Apple Dealer wants $179 for the drive plus $100 for labor. I've googled a few places that have Combo compatible drives for about $129, and so I thought I'd ask if anyone has replaced their own optical drive in their dual USB iBook, and did you do all of the work yourself and whom did you use as your parts supplier and were you happy with doing business with them? I'm tech coordinator for a small publishing company, so am more comfortable than most doing many of my own replacements, but not as comfortable as a full fledged Apple qualified service provider. Joe
