I have a Pioneer PDR-609, and I really like it. It's easy to use, and the copies of CDs sound virtually the same as the originals. Recordings from analog sources sound great too. A friend has a professional recorder. The main difference is that he can make copies of digital copies, and he can record onto any CDR, not just consumer audio CDRs. The price difference between computer and consumer audio CDRs is much smaller than it once was.
I also recommend Mitsui CDRs, but I've also get great recordings on TDK and Maxell.
