I have a Eureka Apex 2, originally purchased for backpacking. It has been a great tent for the past 15 years or so, it was $99 back then. Not the lightest, nearly 5.5# in original stuff sack packaging and with homemade footprint, but plenty of room and I've never had an issue with it. I'd buy a Eureka again, and I see that line hasn't really gone up in price in 15 years.

I just bought a Big Agnes Tumble 2 at REIs garage sale for $99, brand new but apparently missing a piece (something that ties the two poles together where they cross, can replace with velcro). Same sized tent, but I didn't like the rainfly on the Eureka (they have changed it to something better since then) for the high wind environment I'm going to next. Haven't had a chance to try it out yet, but it is about 1.5# lighter than the Eureka. My only complaint is that it's not staying in factory stuff packaging, the poles elongate the stuff sack too much.
