If it was me, and I didn't NEED it right now I'd play the wait game. There's probably a reason they are offering $500 instant rebates on the HD-B 3000's with SHOT around the corner. It's an exciting time for optics, we are finally starting to see some much overdue real integration with electronics, but many products are still lacking heavily in integration. Heck I'd spend the $900 on the Sig 3000 to get me by if I needed something. The next big RF binocular purchase I make is going to have to offer integration with other items. If it's an RF binocular that's offering a firing solution, it has to integrate with a kestrel and a GPS.
While I don't think much of Sig's quality these days, I will say their BDX system is exciting, tie your kestrel to your BDX 3000 rangefinding binoculars, get your firing solution, and it goes strait to the scope with holdover, no dialing, no mess, no fuss. It's long past the time where we should have items as SYSTEMS not individual components. Either scopes that offer rangefinding and ballistic solutions that talk to a kestrel for weather and phone/GPS for terrain, or rangefinding spotting scopes/binoculars that talk to the scope and kestrel/phone etc.
