Fly the Team Iceshanty Flag! Iceshanty Proshop
Don't know how much you are looking to spend, but the Frabill Ranger XL Twin or their new ice cruiser series would make a nice flip style shanty IMO. I have a Ranger Triplex and I use it to fish 2 primarily. Its not too big for one person to set up and not too small for 3, but I have found 2 to be perfect. I just take one of the seats out and store it in my boat so I only have 2 seats and very adequate room. It seems to be pretty well built and pretty durable. I am sure you will get some more ideas from other members with other shaks. I can't say anything good or bad about other brands as I haven't used them.
