Cheryl,
The Tandy CDR-1000 is the Mitsumi CMRC-1000, and if you can get it for
less than $200, it's not a bad deal. The drive is also sold under the
GenStar and Talon labels, among others. It's a low end drive but still is
able to meet the MPC specs for a data transfer rate on 150kb/sec. Access is
slower than more expensive drives, typically 700-800 msecs. I have a
Mitsumi in my setup and it's performed well. If you'd prefer an external
drive, DAK has one for $199 that looks like a good value and it's bundled
with a selection of CD-Rom discs.
