You are right, avoid cheap ones - I've got through about 7 mics so far and yet to find a good one because I've been trying to be cheap.

Tony (@toymaker) recommends the revolabs xtag wireless mic http://www.revolabs.com/products_wm/xtag.htm although it is expensive I have no doubts that it is very capable.

Alternately, you could use a bluetooth mic, one designed for a hands free headset for a phone. I got a cheap one and it didn't work too well (constantly playing up although the mic was great when it worked).

Thanks.... Cheers

Added another alternative after I hit reply too soon, possibly a cheaper alternative.

Ouch, seriously pricey!....A bit out of my price range so I will have to keep looking....

I have had good luck with the Motorola Roadster hands free speaker. It has a noise canceling microphone that is the best I have tried, and the speaker is really loud (probably louder than max volume on the Toughbook). Prices are dropping because Motorola just launched a version 2.

Ha, ha... No Bluetooth in my CF-19, either.... Thanks Alan

Bluetooth dongles are only around $5

Dongle plus Motorola Roadster looks like it could be a cost effective option.

Is the CF-19 going to be on-board the robot? Decent quality wired microphones should not be hard to find or very expensive. (really good ones are, but less than an equivalent quality wireless).
