Here's one (Mortonbuildings.com)
I ended up with a 30x48 Morton building. Super quality construction and a bit more expensive than most but can be taylored to anything you want. The wife wanted something that didn't distract form the house. Mine's got 18 inches insulation in the ceiling and R19 walls but I'm near Atlanta - not as cold as you guys up north. Morton been in business since 1903 I believe and have facilities all over.
