Ok, I'm not into these sort of things at all, but I need advice on the possible purchase of one.
  Firstly, what make should I go for (mainly for doing trackdays & racing)
 Where from? (shop please)
 and how much are these things?
 I have progressed to working the DVD player so far........... 
 C, wanting to shop in her lunch hour tomorrow, if these damn things aint too expensive
