I second the Mountain Hardware - definitely worth EVERY Penny.
I bought a 2 person no name brand tent that weighs about 3.5 pounds, and it had enough room for two people, and we threw our bags at our feet - not backpacking bags, but there was enough room for two duffel bags. I think I paid $30 on Ebay
But for your purposes, I would definitely check out Mountain hardware or Eureka - don't have any personal experience wtih Eureka though.
