I'd opt for either the Marmot LimeLite or the REI Half Dome 2.  

I've been using the Half-Dome 2 plus (an older verson than is sold now) for 6 years of canoe tripping (minimum of 14 nights out, maximum more like 30 per year).  Excellent tent.  Light weight, 2 doors/vestibules, overhead loft, free standing, small window.  I just happened on this tent at REI once ... on the clearance rack for $50 ... best $50 purchase of my life!  The ground cloth for the model was maybe $15.  This model is a tub-design, meaning no seam next to the ground.

On my last outing, I used my new Marmot Twilight 2P which I picked up from Sierra Trading Post for $130 (without ground cloth).  It has similar construction to the LimeLight, but used a more complicated one pole system with 2-Ys toward top and bottom and a cross pole in the middle ... all connected to 3 hubs.  This served me well on my 10 day WCPP solo and kept me dry despite some significant rain events.  This model is not a tub design and does have a seam close to the ground.  I did seam-seal the tent before my trip (I always do), and paid particular attention to the ground-level seam.  It passed with flying colors, but I don't think I ever placed the tent where the water had a chance to pool.  I did use a Marmot ground cloth with this tent, but I had to adapt one from another model because the tent seems to be a discontinued model.

While I do like the Marmot, one feature of the Half-Dome that might make me return to it is the zipper location for the vestibules.  The REI tent is slightly better in not allowing water to drip into the tent while you enter/exit if the fly is wet or its raining.
