By the way, I do realize the weight difference here ... and also the fly issue. The REI tent does have a couple things I like over the Keltys though ... those things being the option of zippering a covering over the screened windows, and as goofy as it might sound, I like the color scheme better. The REI also has 2 doors (which actually isn't that important to me ... just saying ...). So there are a few differences to consider.
