I like the Outdoor Connection products. I have an OC shower tent and a tarp and I'm very happy with them.
I just went to their website to check out the tent you're looking at. It looks good to me. Treated canvas, ventilation, quick to erect, and a 3 year warranty. Very impressive for around $550.
It's probably quite heavy though - not sure if this is a concern to you or not.
