I have a 14" G4 ibook with a dead optical drive (slot loader cd/cdr/dvd). I have found sources for new drives and that are fairly inexpensive....as in under $100. Has anyone on list had experience replacing the drive? It looks like its pretty labor/time intensive but doable. Hoping to hear from someone with some actual hands-on experience so I can get encouragement, warnings, tips etc. Thanks!!! Denny
