I bought a "Zazzy" 4x4, im happy with it. Has 3 bars across the top for hanging stuff. Ive noticed a few pinholes at night, but the zippers are beefy, and the openings seal up nicely. The area I have my tent setup has a sloped roof, from 72" to 70". Since I knew I was gonna hack it up, I went with something cheap. I was impressed when I put the fabric over the frame. There was a lot of stretching and pulling tight, I had less than an inch of room to work overhead.
Once I have a spot where I can get a tall tent, I'm either gonna grab an AC Infinity, or a Covert.
