I haven't yet. I did find a pack but the sale fell through. I'm lookin at either a pair of Volkl 90Eights or Nordica Santa Ana 100s for an AT setup. I'm conflicted on which route to go because I don't have the money for 2 pairs of boots so it seems logical to get a hybrid boot like the techica Cochise. Getting new boots this weekend so will try a pair of these on. If I go the snow shoe/back route then I don't need AT bindings or skins. I'm a bit daunted about getting started. I think I'd ideally love it if someone were selling a full setup with skis/bindings and skins. I've seen a couple for sale but way too tall so hasn't worked out so far. I'd like something around 170-175cm. I only plan to do this inbounds.
I'm stoked you are so happy with your setup.
If you're thinking about uphill at all and buying new boots, you should absolutely get something with pin compatibility. Unless you need plug-boot levels of downhill performance, there's no real downside to the current crop of downhill-oriented AT boots compared to a "normal" alpine boot. There are disadvantages for the uphill, but they're not a big deal in your use case.
FWIW, my wife was happy overall with her Cochises, although she did have a walk-mode switch fail and a boot crack (both addressed under warranty, so she's now got a brand-new pair of boots). She was also much happier after we upgraded the Marker Tour frame bindings on her all-mountain/AT skis to a pair of Shifts.
I'd expect that you should see full AT setups showing up more often now on Craigslist, Facebook marketplace, forums, etc., and probably also a few at swaps. And that reminds me, I need to figure out what I'm ready to list.
