Which one should I get?

[supercellghost]

I've been seriously deciding of getting an nitro truck for a while now, and since this is gonna be my first one, I don't know how to mantain,clean or care for these cars. Since I am on a lower budget, around 100 dollars, I have narrowed it down to 2 ads on craigslist, a Jato, or a Nitro Sport. And now here's the question, Which one should I get??
(little note: something is wrong with the jato, I don't understand what)
Jato:http://chicago.craigslist.org/nwc/tag/1279420000.html

Nitro Sport:http://chicago.craigslist.org/sox/cto/1278734744.html
