Check out a Eureka Zeus Exo 2 as well. Bit of a nasty green, but not too bright (on my computer screen anyways). Seems to fit your other criteria as well. If memory serves ~140$ ish.

I've no experience with this tent, but am also in the beginning phases of looking for a new one.

That Eureka is free standing, single wall. Someone wrote here on the forums that the vents do have to be staked out though to work.
