Okay, I'm in need of a tarp. Upgrading from a blue poly tarp.
Something with decent coverage, mostly spring to early fall weather.
I'd like something under 100 dollars, but the cheaper the better.
Weight isnt really a huge issue.
I'm not sure what shape I should go for, I'd like to have the option of a storm mode if the bottom falls out.

What are my best options?

Thanks for any help in advance.
