Building a Emaxx with BL

[|2evo /\/\an]

Hi!
I'm new to these forums and i saw that there are many BL people here so i thought i would ask a question.
I have a revo now(nitro powered) and i think its nice to have a BL emaxx or even a BL revo too.
So i started to make up costs for the hole thing and im wondering whats gonna be cheaper, a emaxx or a revo?
i think the emaxx needs some driveline upgrades to handle the power, but im not sure what to get so help!!! if the emaxx ends out cheaper, could you guys list what i really need?

also, i think i will be using a 9L/9920 setup(i can get a Feigao 9L cheap from a guy here on the boards) but the controller cost is really whats bugging me! its too expensive since im only 13 years and it would take some time to make the money.

BTW, does anyone have a cheap 9920 or 9918 controller for sale? make offers!

Thanks in advance
Max
