well, Martin made my decision extremely easy... with his permission, I can tell you I got the DigiCell ANYNet from Martin for $150. Add a suitable wall-wart, and a serial expander, my total was under $275 (after tax... I live in Texas... in fact, I picked it up in person). The thing they didn't have was the connecting cable, so I'll have to find a way to get a hold of one of those, although Brandon Stapp is checking with Uplink as well. Even if they want $50 for the cable as inferred earlier in this thread, at $325, the whole package is still less than the retail on a Telular TG-1 (I was recently quoted $395 by the company that ADI referred me to). Plus, to have peace of mind that if anything went wrong, both NextAlarm and Elk officially support the Uplink made it an easy decision...
.. now if only I had that one cable.
