Look at the Quest bilgy pattern - it has a floor, and it's a 2 person.

Spend once. Be happy. It's cheaper to get what you want up front - says the chick who went through four wrong packs, three pairs of the wrong shoes, multiple wrong shelters, and several versions of cooking kit. Glad I only got one spectacular failure in sleeping bag to get what really worked out.

I would get the kit for the 2 man with silnylon 2nds - the 2nds have cosmetic blemishes but I have a tarp made of seconds that's pretty darn good, kept me dry lots of times. Yes, it's more expensive. Somewhat. But it's 2 lbs 4 oz and you can't really beat a nice roomy shelter that doesn't weigh 5 lbs.
