My knees have started hurting enough that I broke down and bought trekking poles, so now I want to ditch my tent with poles and get something supported by the trekking poles. So far I've found the SMD Lunar Solo, Tarptent Squall, or Tarptent Contrail. If there are any others you recommend, I'm open to suggestions. I've never tried camping under something like a plain 8x10 tarp in GA during the summer...can you do that in the southern appalachians without getting overrun by bugs? It's so much cheaper of an option, it may be worth trying.
