I think that in-ears disconnect you from your congregation, and need a VERY critical balancing of the mix that it is fed. A hotspot type monitor is a LOT more forgiving, easier to adjust on the spot (you in ear mix is going to be controlled by the mixer) and, if bad things happen, feedback or a sudden blast from an incorrect patch or registration isn't going straight in your ear canal!

I have two of the Mackie SRM-150's. Yes, they are a tad pricey, but you get a LOT of options that other hotspots don't give you. They are also weak in the bass area (something that is actually a PLUS in a monitor). It is altogether way to easy to muddy up your sound, and play much louder than you need to be with bigger monitors. The Mackies, to my ears, provide JUST what you need, and little of what you don't, in a compact and well designed footprint.

Highly recommended.
