What's the best guitar wirelss system (by personal use) for around $250ish? Used or new

I dont really recommend wireless systems. Theyre all tone suckers, and most create bad buzzing.

But check out some of the systems by Samson. They make some of the best out there, IMO.

Im having trouble finding what my friend has right now on the internet still searching but you dont really have to even spend that much my friend got one for $100 and it is great reaching over 50 feet. but yes as the guy says above me wireless systems can tend to take away from the sound. i still choose to use chords over them.
