I got a Kyosho ZX-5 on here, got two cars for £175, batteries cost me £50 for two 4900mah trakpowers, got an XErun off ebay for £100, and that was me sorted (I had a servo and stuff).
You said you don't wanna go 2nd hand, so you could get an LRP Blast which can be got for about £135 in the right places. That'll give you everything you need to start, then if you want to upgrade, £100 on an Ez/Xerun system on ebay, could get a couple of Lipos for about £50 each, then if you needed it, a new servo for about £40 and that's your budget maxed out.
EDIT: Forgot you needed a charger, you could ditch the servo and get a charger instead
EDIT2: Should have checked the OP date... d'oh!
