single rechargeable wireless mic?

wondering if theres such a thing as a single, rechargeable, wireless microphone that i can plug into my hercules rmx for those karaoke faithfuls?

had a little look and all i can find are dual mics that kind of break the bank a little...

thanks in advance! 

Hello,

I always use a wired microphone, but if I was looking for an affordable but flexible wireless microphone solution, I would use the Alesis MicLink Wireless,
- its price is reasonable
- you can connect any microphone which has an XLR plug,
- the wireless receiver output is a line output so you can connect it on Rmx mic input (and set it a low volume, otherwise it will saturate).
