If you want durability, you can't beat an REI/MEC warranty. My buddy and I picked up an REI Halfdome T2 HC (old mouthful of a name) and at around 5 lbs it's not super ultralight. However it fits both of us and our gear (we're both 5'11" range) without us having to make our friendship any more intimate. Best $20 we ever spent (REI Garage sales are awesome), however even at the $190 MSRP that a new halfdome 2 runs, it would still be a worthwhile tent.
We use it in desert scrub and as long as you pick a decent camp site and clear the floor of anything spiny we have no reason to worry about durability. Also, if it fails on you in a disappointingly fast time (say under 5 years of casual use) you can always return it for a full refund.
It's incredibly simple to set up, not too bad weight wise at 2.5 lbs per each person, reasonable price backed with superb customer service.
If you want something considerably lighter then you usually end up sacrificing durability (UL fabrics), increasing price (SUL tents, hitech fabrics), increasing fiddle factor (tarps or non-free standing poles), decreasing perceived comfort (floorless shelters bring out bug/critter fears), or any combination there of.
