I've fished in one many times and it's a nice shack. You can now find them at Cdn Tire occasionally on sale for about $350. If you are in Saskatoon, I believe North Pro Sports sells them and according to their website they are on sale for $327. Great deal if you ask me. If I didn't already have a shack, I'd be picking one of those up. A sunflower heater heats it very well. Not sure on the big buddy, but I don't see why it wouldn't. I can tell you the regular buddy is not enough for such a large area. We've set it up in some good winds before. You just need to make use of the ice anchors. Buy some new straps for it though as the shoelace type strings they send are not sufficient. The shack seems a bit "tight" though and the doors seem stretched quite tight. The bag can be a bit of a problem as it was quite the fit after you've had it out on the ice and it's all frozen.
