Well, I just got my first very budget set up, and it works. I got the cheap Shure 112 and some foam tips. I have a SM57 across the room going in a cheap-o 4 track mixer and take the headphone out, then some earmuff from work on top of that and it really is very quiet sound almost completely from the mic. Without the muffs it is a mix between bleed and mic but still lower volume.
The practice room is the main place I need protection because it's little and the guys actually play louder at practice than at shows so, good deal. Plus better perspective of my mix. Haven't tried them out at any of the spots we play that have big sound system, but I'm sure they will be fine and gentler than a wedge. If they have no option to plug the buds in, I can take my practice room setup of mic and mixer and use it.
Thanks guys for recommending, I know it isn't really exactly what you recommend but the volume reduction is available to me now and I can hear everything fine. I probably spent $100 US, I already had the mic and cable
