To Collide or not to Collide, that is the question...

Now that there is some stability with levels 61-939, someone needs to put together a calculator online. A user would be able to input their multiplier, their total cash, etc. and then see different scenarios for if they, say, buy 24 hours of Collider and 100 rat trap trucks. I know this wouldn't account for XP via their buildings, etc. but it would give a general idea.
