Thank you for all of the suggestions!
I was hoping someone might say, "Oh yah, I have those, they work great." But I would rather have no wireless, than crappy wireless. My first choice would always be to go with the Shure
LX, because I have used them before, and know that they will work problem free. I was just hoping to find something less expensive, because our budget to buy anything for our musical is very low (The story of every high school), and our singers are VERY bad at projecting their voices.
