It sounds like you're on the right track with the Chorus mix you're thinking about (especially given the price), but I just want to echo what others are saying here. Stay away from Power-Shift (only one cog downshifts eliminates one of the major benefits of campy) and Power-Torque (forget about easily maintaining these as you need a gear puller and special Park adapters and it's still a major PITA). Given that, if you want a slightly less expensive (than full new retail, not your good price) 11 speed kit, get a Chorus shifter and crankset and Athena everything else. If you are looking at 10 speed, search for some 2009/2010 Centaur.
