Money can buy lighter weight shelters, ie. Dyneema/ Cuben Fiber. Less money = sil nylon/ polyester.

Less money = Tarp shelters akin to floorless tents.

Personally, If I was unaccustomed to warm weather tarp or floorless, I would go with a more traditional tent for late fall.
If you want to camp this summer with a tarp and get caught up on the learning curve and idea, go for one this fall.
I like hammocks for a couple reasons when still hunting deer.
That's not a decision most make, but I have unique situations and experiences. That makes my choice a tarp. With the additional underquilt, the weight savings is pretty much a wash.
For ground sleeping, experience with site selection is critical. You can imagine as rain can ruin your sleeping bag.
