I've desided to pick up Ninjago because the mimifigs are epic. however, I want to get the most minifigs for my buck, what sets would you guys suguest?

Kia's fire mech. Only comes with two minifigures but then again it's only $12.

9449 - ultra sonic raider. six figs total, including all four ninjas and the exclusive pythor. currently on sale for $61 on amazon (24% off), with free shipping and depending on where you live possibly no sales tax. pretty good set and value for your investment dollar. i was lucky to stumble upon five of them on clearance at shopko for $32/each plus tax. i plan on selling them this christmas season.

I think terrymc4677 is right because getting all four of the ninjas is awesome!!! But the coolest part about this set is probably Pythor P. Chumsworth!!

ultra sonic raider is now down to $57.99 on amazon (28% off).

Kai's fire mech. Only comes with two minifigures but then again it's only $12.

The normal retail at every retailer is $9.99. It's only Amazon that has it listed for $12, of which I have no idea why.

It is a nice little set though.

Like terrymc said, Ultra Sonic Raider has all four Ninja ZX and the exclusive Pythor.

If you are after minifigs, then the Ultra Sonic Raider gives you the best for what you outlay right now. If you are looking at it from an investment standpoint, you want sets with dragons in them.
