Not cheap, but cheapest it's been as far as I know and much better value than the stupidly priced second hand market for the older controllers.
Works with Rock Band 4 ($15 @ Xbox) or Fortnite Festival. Apparently works with CloneHero on PC but haven't tried it. Came with a wireless dongle for the Xbox and also connects and charges via USB-C.

The newest guitar in the market allows you to play music like a true rock star now on Rock Band 4 and Fortnite Festival as soon as Rock Band 4 guitars are supported. With a unique design that is suitable for both left and right handed guitarists, everybody has a chance to dominate the competition.
Enjoy elevated comfort and convenience with a 30-foot low latency wireless connection, a built-in, rechargeable battery for up to 36-hours of play per charge, shoulder strap, and patened pending analog stick. Turn it up to 11 with the 3.5mm audio jack, and adjust volume on-the-fly with the audio controls located on the D-pad. The guitar is also collapsible allowing you to pack it for your next tour or safely store at home. PDP's RIFFMASTER is officially licensed by Xbox and compatible across Xbox Series X|S, Xbox One, and Windows 10/11.
Just in time for Easter.
