One thing I learned about tents very early on is to go to REI and try them out first. Online it doesn't tell you how easy or a pain they are to put up and if they have quirks when doing so.
Also you think you might be saving some cash with a no name tent but they end up costing you more in the long run because of quality. This is something that you are going to bring up and down constantly so you want something that will hold up the abuse and a company that will stand by it in case something goes wrong.
