I like the Stephenson/Warmlite tents. They're not cheap, but the quality is excellent. If you are 7 or 8 feet tall, no problem! They are not freestanding and not made for small ledges on big walls - they are fairly big, but they do make a shorter climbers version that I have no experience with. Lots of room in the standard version. 2 man tent ~ 3 pounds. Excellent in high winds. I've never had mine in heavy snow, but if planning on a lot of heavy snow it might be worth adding a 3rd hoop which would cost a tad more. They're made in Gilford, New Hampshire I think. Be sure to do the water proofing they recommend. I've had mine over 10 years with no problems. Read ALL the info on their website if you think you want one. They tell you the plusses and minuses and they are right on the money. 2 people can fit with no problem, but 1 person can carry expedition gear and put it inside the tent. Aluminized inner wall recommended for added warmth - it does help.
I'm 5' - 11" tall and when I was trying to decide I really wanted the Bibler Eldorado or the I-tent (can't remember which was longer), but I got inside and I knew if I got one that my sleeping bag would be touching one end or both and it would be wet, so I went with Stephenson/Warmlite 2 man with lots of bells/whistles and it cost ~ $500 10 years ago. Money well spent. Every one is custom - color, how many doors, 1 or 2 wall, 2 or 3 hoops, windows or no windows (I got 2 windows but rarely use them), etc. Remember, your sleeping bag will be 12-24" longer than you are. A short tent would work for 1 or 2 night trips, but you'd want a longer one for a week or more.
