Ha! That's a funny evolution. Start low and work your way to the top tier.
Are you looking at the Standard MacCat at $95, or the Deluxe at $115? The Standard doesn't really give you all the extra room you seem to be looking for from a tarp. You can cook under it, but don't spread your stuff out too much. The Deluxe gives what seems like a lot more covered space.
If your primary motivation is max covered area, the BMJ will give you more covered area than either of those options. If you go that route, be sure to order one with the panel pulls. They really allow you to open up the tarp so it's nice and roomy on the inside.
