Advice for buying first 1/8 Rallycross

[Brooke]

I'm going to buy a 1/8 buggy to complement my Associated B44.1 but don't really know which one to buy. I've been thinking about the Associated RC8b, Serpent 811 and the Tamiya 801X.

Can anyone give me some advice on which of the's would be the better car or even maybe recommend a better one without the prices going through the roof?

Cheers for any help
