This one is realistically just short of 5lbs with the stakes and all. I won't say it's cheap (About $550 when I got it but I was one of the very first. I saw it for $420 on Backcountry and would buy it again for that in a heartbeat).Price, however, is a much more restrictive issue for most people including myself. I was fortunate at the time to be able to update almost all my gear at once.

Btw, I looked at the BA Scout series (the one with the big vestibule really caught my eye) but like you said, the mixed reviews kind of nixed it. There were a lot more negatives than positives and if I have to go trekking pole I'll go straight to Tarptent.

Weight wise you listed one at 3lbs 10oz, the one I have in the pics is about 1lb heavier. Given that it's half again the tent plus the vestibule from hades it's 1lb very well spent. Can't get around the money though. It's just not a cheap tent since it's virtually new while others have been out for a few years (and are still tops of their class).
