Thanks to all for the replies.
The reason I wanted a CD-ROM drive is I've been using WinUAE to play my old games for years. I don't have any Amiga games around any more and I assumed there'd be some way to get these .adf files over to the Amiga, either to load from HDD or to get them onto Amiga floppies.
What's the quickest, easiest or cheapest way to get data from a PC over to an Amiga these days?
Thanks again to everyone

Well, you've certainly got some nice options then. The Blizzard SCSI kit and SurfSquirrel/SquirrelSCSI are pretty hard to find, but show up on ebay once in a while. That's if you want to use your SCSI CD drive.
You can get the PCMCIA Compact Flash adaptor from Amikit, which is an easy way to transfer files back and forth.
Amikit also sells the USB kit, so that you can connect all sorts of devices, CD drives included.
Another way is with a null modem cable and Amiga Explorer (included with Amiga Forever), you can move files back and forth between the PC and Amiga quite easily.
A few people have done a little modifying of the 1200 case and installed a laptop CD drive inside, since it uses IDE.
