Is this a good motor for an e revo?

[JThiessen]

Thanks for the "welcome's". I've been lurking in and out of here for a couple months - mostly drooling!
I've finally had my fill of trying to get my 2.5R to run right, so the Revo is going electric. I'm just not sure if I want to make the jump to brushless or not. I had an Emaxx a while back, liked it, but I had to sell it to be able to buy the Revo.
So here's a few more questions. I know that there are ESC's capable of controlling both brushed and brushless motors. Are these decent units? Can they typically control (2) brushed motors like an EVX can? I think what I may be leaning towards is something that I can switch back and forth from. I'm just uncertain if my reasoning is based on facts or hearsay (hence my first post!). Are brushless systems much more susceptible to moisture issues, dirt, and general contamination than a brushed motor is? Thanks for all the advice in advance......I know the steep part of my learing curve is ahead of me on this subject...
