I'm not sure I agree about Power Shift being trickier to work (especially just switching brake levers- their identical), the internals seemed to come apart in a similar way for both the Athena (PS) and the Record/Chrous (US) I worked on as well.
The point about getting a really nice pair of brake levers for effectively £20 is a good one though, I think that would swing it for me.
