I've had a Lunar Duo for 4 years now and love it. It also has 2 doors and vestibules. It's held up quite well though I don't get out a lot with it (I tarp when solo). Just survived torrential downpours on a flooded tent pad in the Smokies and our's was the only one in the Troop that didn't get water in it. That's with just the 30D floor, too. I had patched 2 tiny holes I'd gotten in the floor (I also don't use a groundcloth). It's a true 2-person. 4 people could sit in it to play cards if necessary.

The 2 main downsides (assuming you already carry trekking poles):
1. single wall so you may get more condensation than one of the others depending on location and conditions
2. not freestanding so you must stake everything (6 stakes). Very simple to pitch.
