The 600 and 700 series bot list as current product lines on the website, whether they are in currently acceptable US frequency territory is a different story...
Rumour has it that the PSM1000 is not far off which will be top of the line...
What I want to see is someone implement a backlink so that you can monitor the receivers, that, my friends, would be cool...
Or how about implementing RS232 control of the beltpack so it could be integrated to a digi console so the monitor guy can hear it as it sounds, the control being to switch channels on the pack, using something like this supposed revolution of CueMode on the 900s
