My 4 season is pretty rock solid, but it's not very light. It's made to stand up to more than I've done with it. It stacks up to 12 lbs with everything in the bag. I haven't bothered yet to go for lighter stakes yet. It's the Eureka K2XT. It's a spacious 2 man with 2 vestibules, the front being very big with a clear plastic window. It was around $400 when I bought it. The only time I saw condensation was when we had a night of rain at 35 degrees, and it was hardly noticeable. More than enough space for 2 people, carrying a total of 100 lbs of gear, and lots of places to store your items in the mesh cargo pockets!
