Ozark 20x11 tent, coleman montana, colemen bayside...do you own one, what do you think?

Hey there, Buying a CHEAP BIG tent, i realize that none of these tents are particularly weather proof and i am not looking for the "best tent money can buy" I just want to know if you have one of these tents what you think of it.. easy to set up? holds up in not so nice weather? ventilation? We are using it for music festivals in HOT weather... Thank yoU!
