I would also have to agree with buying a good quality tent once and always sleep dry and comfortable. And I would also have to agree that camping saves a bunch of money.. especially when you find free places to pitch your tent. Having slept in motels and pitched tents, I much prefer tenting...
I bought the Eureka El Capitan 3 and it's perfect for my uses. It has 2 large vestibules, excellent venting, can be free standing or staked in, is totally waterproof, uses fiberglass poles with clips and sets up in about 5-10 minutes. I bought it at Lebaron in Miserysauga.

I have a MEC Hummingbird 3 (2 person) tent. I like it, big enough for me and my gear and that's it. Kind sucks to put some of my gear on in it though since it is low and long.
I think the next tent I will get will be a free standing tent, that way when I set it up I don't have to stake it down like mine does. Then I could pick it up to shake out the dirt too.
