I have a Cambridge 740c and have had no problems, great machine. Problems with the 640c are well known, the ribbon cable would become dislodged leaving the left channel dead, subsequent models are supposed to be free of this problem. I had a Rega Apollo for a couple of months and sold it, it was not my cup of tea or maybe it was my system. Problems with the Rega player are also well documented, there are many that have had problems with the software causing the machine to do some crazy things, there is one report of a Saturn that played the music of a CD after it had been removed from the player and a different CD loaded up, it did not play the music from the loaded CD. I also did not care for the plastic face plate and the less than responsive control buttons. Also keep in mind that the warranty is not transferable with the Rega's.
An outboard Dac with a less expensive transport (DVD Player) would give you a lot of flexability, a Monarchy Dip can always be thrown into the mix if jitter is an issue.
