Welcome to the forum.
Since you are looking for an 'all in one' solution to try, and want to minimize cost, I'd say look into one of the double-layered hammocks with an attached bugnet. Perhaps one of the Claytor
models is a good choice.
The reason I suggest a double-layered hammock is because hammocks require more forethought into 'bottom insulation' than a tent. Using a DL will allow you to easily use some kind of sleeping pad (which you likely already have) between the layers of fabric and not have to fuss with the pad sliding around. However, if you don't like the double-layered models and still want to use a pad, check into the Speer SPE
. Of course there are other insulation methods besides pads (underquilts), but they are a more expensive approach.
Good luck. Feel free to ask questions and let us know how your experiment goes.
