I use to have a Losi xxx that i raced. Was a great car. Did a couple of nationals with it, along with plenty of reginals/club events.
Dont get a Tamiya or Traxxas... from what iv seen they fall to bits.
Losi, HPI, Associated and Schumacher would be my personel recomendations for something of good quality. (Try looking second hand to keep within your price range)
