CD-RW recommendations

[D-Man <dsh8290@rit.edu>]

I just saw an ad for a local store in the paper.  They have 3 CD-RW
drives on sale.  What do people think of them?

$100 (after rebates)
Acer 12x8x32 Internal CD-RW  ,  part number in ad: CRW1208A

$200
Iomega 4x4x6 USB CD-RW  ,   part number in ad: 31475

$250 
Yamaha 16x10x40 CD-RW   ,   part number in ad: CRW2100EZ
    If I get the Yamaha, I can get 128MB PC13 RAM for free (after
    rebates)


I don't know if the part numbers in the ad are for the store (useless)
or for the manufacturer (useful).  What do people think of these
drives?  Does anyone have any experience with any of them?

This sale ends tomorrow, but I don't _need_ to get a drive
immediately.

Thanks for the input,
