Agreed about the BCA beacons. The Tracker/Tracker2 are super easy to use. The Mammut Barryvox is really nice as well, but it is more expensive and takes a little more time to understand. I have only used those three so I cannot comment on any other ones.
Don't forget shovel and probe though! Those are equally important. I haven't noticed a difference in probes from one company to the next, but shovels vary a lot. I don't like the BD ones. BCA makes nice ones but they can be on the heavy side. The Voile one I carried on one trip was way too big. I purchased a Mammut Alugator lite and it's been great.
Make my day.
