The RRP of that group is over a grand, although Merlin have it discounted to just over £500, but out of stock.
You should be able to strip it and shift the remaining parts for...£300-400(?) I reckon, meaning you get a brand new Force 22 groupset for £600 if you're clever.
Regarding SRAM, I notice you can get a full Planet X RT-57 with Force 22 for £999 (http://www.planetx.co.uk/i/q/FBPXRT57FORCE22/planet-x-rt-57-sram-force-22-road-bike)
