Did a search, and the last time I could find this topic discussed was 2011. I assume there have been some changes since then. Are wireless capable of giving the full tonal range of a wired systems? What are people using ranging from "best" to great sound, but not crazy expensive?
Line 6 G30 works for me. I use high capacity rechargeable NiMH from Harbor Freight in it and get almost two complete shows out of them. They fall about 15 minutes short. I recently ordered some ultra-high capacity NiMH AA's from Amazon to see if I can close that window. My $.02!
