There are at least 4 or 5 good ones to choose from:
Frabill has the Ranger XLTwin(has separate seats) Set-Up: 96"L x 64"W x 67"H Weight: 90 lbs
and Ice Cruiser 200 which you provide your own seating.Set-Up: 96" L x 63"W x 67"H Weight: 62 lbs
Otter has the Medium Cabin(can have separate seats or a bench seat or provide your own). 65"L x 84"D x 70.5"H Weight is 60 pounds before any seating choice.
Eskimo has the Quick Flip 2 Deluxe with a bench seat. Size: 60" x 84" Height: 68". Weight: 88 lbs
Fish Trap has the guide (with separate seats). Size: 81” Long X 60” Wide Center Height: 60” Weight: 82 lbs
Shappell Rover 2.0 DX with a bench seat. Size: Set Up-66" Wx 88" Dx 72" H. Wt.: 71 lbs
If you normally pull through a bunch of snow, I think the Otter, Eskimo, or Shappell pull easier because of their higher sled design.
If you want the most bang for your buck, I think the Fish trap is the way to go.
If you want the strongest built, I think Otter has that with their square tubing and super sturdy sleds.
If you prefer a bench seat, then only Otter, Eskimo, and Shappell have those.
It all depends on what you're looking for, your budget, and what's available near you so you can actually go see them and sit inside them before you make your purchase. See how comfortable both of you will be while sitting in them. Make sure you have enough room for yourselves and everything you will bring.
Just my 2 cents worth.
