I owned a Rega Apollo with my B60. Excellent combo IMO. They're $1k US new, and about half that on the used market.
I sold it for a Rega DAC (fed by Apple TV 1). A great self contained hard drive based system. And yes, I still buy CDs and LPs.
The Rega DAC is also $1k US new, and quite a bit better than the Apollo. Not as cheap second hand, as they haven't been around very long.
There's a review of the B60, PMC DB1, and Rega Planet 2000 on Bryston's Website (the Tone Audio review in the B60 page). That'll give you an idea of what the Apollo sounds like with the B60.
