You don't need to spend 600 bucks to get a 3 lb. tent. On the other hand, I've seen some new 100+ Keltys fail miserably in a downpour, whereas; my 300 night use Big Agnes Fly Creek stayed dry. Apples to apples, same storm, same campsite. I see you live in Colorado. If you plan to take the tent in the mountains, expect them to be subjected to high wind and severe thunderstorms. Cheap won't survive. I was miserable on many trips when I was younger, from the extreme nature of the trips, or from not having the funds for better gear. My absolute love of being in wilderness overrode the discomfort. You need to decide where your limits are. Your girlfriend may have a different take. If you do go out with cheap gear, just remember- getting soaked in the middle of the night , miles from the trailhead is a recipe for hypothermia. Whatever you buy, test it in the backyard or car camping first.
