Matt, some of my favorite tents have been the type you describe with the zip shut windows. I still have several 1 and 2 person Moss tents that I hope last forever. I recently needed to find something that our 3 person + dog family can fit in and after much research I picked up a Marmot Limestone 4P. It doesn't have the zip shut windows, but it does have less mesh and with the fly on and vestibule closed, it's not very drafty. I realized that I wouldn't be camping in this thing in really cold temps with the family, so it was a good sized, inexpensive option. It's also light enough that I could carry it backpacking. Many of the 4 season 3-4 person tents get pretty heavy.
