I just went through the same prediciment myself. I looked up so many tents I was starting to dream about them at night! If your looking for a tent that easy to set up in the rain your most likely going to be looking for a single wall tent. In the end I went for the 'Bibler Ahwahnee Tent'.

Being able to set up from inside the tent gets you out of the rain. The big factor that turned me onto this tent is the two full zip down doors and the option for 2 vestibules. 2 full zip down doors takes a 4 season tent and still lets you use it in the summer.

That being said, I'm sure you can find other awesome tents for less money. Depends on how much use you plan on getting out of it!
