I've got the Collett communicators and I agree with Digi - proper working VOX and clearer communications than the Chatterbox.
Things get difficult to understand at high speeds (wind noise I think), but I've been able to use my VOX properly all the way past 200Kph without any problems. Chatterboxes will not work past 100ish.
Only $139US, they're located in Canada, and I'd be willing to let anyone try mine if they really wanted to try before buying.
