Can you back up and explain WHY you want to use in-ears? Why do you think that's a good idea, and one worth spending money on? Other than the fact that you need different mixes for each member of the band when wearing ears, what do you want out of separate mixes for each member of the band?
well, we think that we can improve our performance that way while having less gear to carry if we can go amp- and cab-less on stage. furthermore we want to try playing with a click and overall, the sound for the audience should be better without amps on stage. we play dropped A-tuning and stagesound has always been a mess that way.
but it's a justified question whether it's worth the costs and effort in ear monitoring involves.
