John,
Coleman make IMHO about medium quality products and this looks to be about that. Neither disaster nor top notch. For instance the fabric is rated to 2000mm (150 denier) but Palin and Kathmandu use 3000mm fabric (190 denier). So, you will be nice and dry unless it rains
. No, just kidding, the fabric will probably be OK in all but the worst conditions but in that case you probably wouldn't leave home to go imaging. [I have been in my Kathmandu 3-person dome with it bucketing down and never had a drop inside. It's also handled 1cm diameter hail and gale force winds.]
One thing I'd look at carefully is the zippers. These are commonly the weak point and large zippers may not be cost-effective to replace. Then look at the seams, which should have two rows of close-spaced stitching, and the peg loops, whose design may vary but should inspire confidence.
Design-wise I have no personal experience with integrated frames but have heard that they can be like wrestling an octopus when packing up. I believe that also take up more space when packed, which makes intuitive sense. I am wary of any design with internal poles as the pole rubbing against the fabric can help water get through the fabric, at least that was the case with crumby nylons tents I used years ago. Perhaps newer fabrics don't do this but I'd need to be convinced. Of course setting up in 30 seconds is bull. I count two external poles, three guy ropes, each with peg, and 6 pegs for the tent body. Think 10-15 minutes, which is reasonable anyway. I can erect my little dome in 5-10 minutes. Lastly, whatever tent you get, get a cheap tarp to go under the floor to protect the floor and increase it's waterproofing and lifetime.
