I would spring for the Ortovox S1+ as your beacon.. honestly is the best beacon there is..
its easy to use..compact...excell's with multiple burials and has a digital monitor showing you the direction to the victim in relation to your location..
other then that... BCA or Voile for Shovel and probe unless you have enough coin then bye black diamond everything (except beacon) so just shovel, probe, snow saw..
also a snow study kit from Brooks Range or BCA can be helpful if you are getting into avalanche forecasting or just enjoy geeking out on snow science as well
