I have used the Coleman Instaclip version, 9x11 for 2 seasons camping and at home. It is basic with screen walls, 2 of them zipping away and no floor. Harder to put up than an easyup but lighter and smaller. Selfstanding, no guides lines required although it can pick up in heavy winds. An ice chest worked for us to hold it down.
It was inexpensive but the steel poles are starting to rust at the connections. It also has screen burn from fire embers and generally it has been used hard and put away wet. I was happy with it given the price which was under $100.
I just purchased the newer version at Costco.
Around $40, it is 12x12, 22lbs in a carrying case.
Northpole (by Coleman?) brand.

I expect to get another 2 years out of it. It seems to be a great price for something that will be used hard.
No, it isn't sold on costco web, just in the store's seasonal camping section now.
