Which wireless lavalier mic set up is best for me?

I need to purchase a wireless lavalier mic set up for an upcoming project I'll be doing. I am familiar with using the Sennhesier ew112-p G2 set up. I would like to have an identical set up, but if I could save some money that would be nice. It must have the capability to attach to a camcorder via XLR. Thanks.
