I got a Wild Country (part of a company called Terra Nova) Duolite, I got it on sale for $170 off of Amazon.
It's on the heavy side, about 6lbs, but it's free-standing, the inner and fly are connected together, the frame is outside the fly and the inner lining is the heavier, white material, not bug netting.
I specifically looked for those features because I wanted something that would:
a) be quick and easy to put up in a cold, gusty rain, you just lay out the tent, put the frame up over it and clip the fly to the frame;
b) something that didn't require stakes to stay up if I was in area that didn't hold stakes well and;
c) the heavier material is warmer in the mountains in the late fall/winter.
It's also got a vestibule in front, my ruck is a tight fit, but it will fit.
Definitely get at least a two person, Wild Country has a single person version of the same tent, but they must have used Japanese midgets to size it. Me and my sleeping pad take up most of the space in my two-person tent, so the single person would be more like a bivy tent.
