I ruined a standard GXP bb in about 2 months and have been running a Hope with GXP shims for the past year, would recommend - well worth paying the extra. The Hope bb is Shimano type (24mm axle) that needs shims on the non drive side to run with GXP cranks, so I can't see why you couldn't use a Shimano BB with the Hope shims as a cheaper alternative
