I've had a Mountain Hardware Hammerhead 3 for I believe eight years now, and I could not be happier with it.  Simple setup, lightweight, and just a beautiful tent to sleep in.  It's been on BWCA/Quetico trips at least once a year since I've had it, and it's still doing exactly what it should be.  I prefer the 3 person tent to sleep me and just one other person, as things are just a bit more comfortable with some extra room.  There is certainly plenty of head room as well.

It's a bit pricier than what you've mentioned (looks like around $300 now), but this website has it for only $236, which is not terribly far away from what you're thinking about:
