I think the Philips was recommended to you because it can handle the latest copy-protection called SafeDisc 2. However I would advise you to get an ACER which can also handle this protection and is a lot better. It lacks in reading abilities but if you would use a different unit for this like a Toshiba DVD you can copy everything...
A Plextor is always a good choice but most Plexie's cannot do the SafeDisc 2
A good reference guide would be the CloneCD Hardware Requirements: http://www.elby.de/CloneCD/english/cdr_a.htm
Look for a drive that supports:
-RAW-96 Reading (both audio and data)
-Correct EFM Encoding (for SafeDisc 2)
