Coleman Dome 4-person tent, available at Amazon for $89.99
If you're camping with a group of people, you'll want a tent that everyone can sleep in.
This four-person tent is easy and quick to set up, and has two doors, one of which opens on a hinge like a traditional door. The floor of the interior is also curved like a bathtub, corners are welded tightly, and seams are covered so rain can't trickle in.
