M-Audio Delta series cards run $500 US for the 1010LT , and $800 US for the 1010 with the rackmount breakout box instead of just a mess of cables.
The RME Multiface is a little bit more expensive, but comes with ADAT capability, while M-Audio charges another $200 US for it, and it doesnt look as nice.
Either way you are looking at $1000 US , or around 650 pounds
Ebay is a bit cheaper, but you sometimes never know what you are going to get, or whats been done to it previously
