If you need one, they work okay, provided you get one of known good quality and set it up properly. Have spec'd some for touring stage musicians and once setup, never got a callback. Brand is not that important, you really don't have that many brand choices out there anyway, actually.
Interference with other devices is a non-issue in the realworld, due to the design nature of the transceiving system, which is digital signal looking all the time for ack/nack or some other parity scheme. MIDI data is rather light in the bandwidth dept. by today's standards.
Then you can break out that 80s era Keytar and prance around with the gitter pickers...
