I bought myself a RC8Te for about $425 :
Slightly used RC8Te roller for $250,
$100 for Neu 1515 1Y Finned in good condition,
$75 Good, but used MMM

You need?:
Roller
Motor
ESC
2 LiPo's / sets of LiPo's
Charger

You want:
- Offroad bashing (fields/grass/gravel and just general driving around some woods) 1. Truggy / 2. MT
- Bit of crawling 1. MT / 2. Truggy (Rock crawling with a truggy = no go since the diffs are often filled with thinner fluid than a MT.)
- Street 1. Truggy / 2. MT

A truggy seems to be the best bet, unless you like wheelies a lot.

You will definately have to look at used stuff (I mostly buy used stuff, often in good shape but just a fraction of the new price : I'm a student), but even than it will be hard when you need all the above...

Some guideliness:
Roller : $150
Motor : $100
ESC : $100
2* 4S LiPo's : $120
Total $470
Sell the E-Revo roller and invest that in a charger

Keep in mind that you will need tools, temp gun, maybe a LiPo voltage checker and some other small stuff.

Just keep your eyes open on eBay and RC-Tech. Especially on eBay you can get lucky :)
