I have to echo the previous post about the new LRP buggy...have a look at its thread on here,

and on modelsport Uk...am pretty tempted myself!
Seems like its abit of a belter!! and for £140, you have plenty left in your budget to go brushless and for lipos, charger etc!
I have a B44, its awesome, but ur looking at £500 for it with a b/l combo lipo n charger!
