na, if you're looking for handhelds I'd probably go with a Garmin. It's what e'body else buys and they've been doing it the longest probably. That's what we used 6+ years ago as one of many ways of testing the integrity of site transmission.

I'm only the most familiar with Trimble and Ashtech as they were the two transciever type units we used the most. But since you're budget is $300 and not $30,000, I'd probably go with Garmin.
