Light and inexpensive, thats a oxymoron. Well, not really, but close =)
I think Smee got it right. Their 8x8 tarp is pretty light and fairly inexpenisve. Although, I sure I you look hard enough, you might be able to find a silnylon tarp say 6x8 (pitched on the digional for hammocks) faily inexpensive. The MacCat Mirco is only $65 as well. You might be able to make a DIY tarp fairly inexpensivly.
