i ski in southern vt and i own 191 caylors, 192 garbones, and 186 billy goats, i find fat skis to not be limiting at all on the east coast, i think they're incredibly fun to ski
tahoes are great ec groomer skis, they ski great on icy days with a race edge on them when i want to just tear up mt snow, however i just don't see them as a pow ski, too much sidecut and camber and everything, they do fine on pow days but they aren't as fun as other options
i rode jj's a lot on the east last year which is why i'd recommend billy goats or something of that type, don't let the waist scare you away, the taper also makes them turn on a dime in tight trees and everything, the whole elf shoe type shape is ridiculous as an ec one ski pow quiver
based on discounts, i'd recommend bacons.  they do not ski like something that is 115 underfoot, they're super easy to turn on the groomers, fun in the trees, and forgiving.  while i see the jj shape as an expanded bacon with more capabilities and versatility, the shop deal is hard to pass up.  i rode the bacons a bit as an ec pow ski and they were pretty fun.  i think if you get blends or something they're just gonna feel like slightly large park skis but that's it and they won't be that fun in pow
just my $.02, don't let location limit your ski choice, i love fat skis on icy ec groomers, just adds some spice to a regular ski day
