Looking to buy, CDRWDVD combo under $200

[^NoLaN^]

So far I've found the Iomega ZipCD 6x4x24x4 ATAPI DVD CD-RW for $100, the Toshiba SD-R1002 4x4x4x24x for $200, the Samsung 308BEB 8x/8x/4x/32x at $170, Ricoh MP9120A 8x/10x/12x/32x for $260. Has anyone used any of these drives, I've read some reviews online for the Toshiba and Ricoh, but those are more expensive and I was considering the cheaper models. The samsung seems the best deal, but I can find very little information, even on samsung's website about the drive. Can I get some input?
