Hi Antony,
  Unfortunately Carole Nash only offered me £14 off my policy for having an alarm fitted so it's probably worth my while having a go at it.  
 I had a search on the board and the datatool vs meta debate comes up about 50/50, I just thought it might be easier to swap my dead datatool with a new one in case they used the same points on the loom. 
 If I could find someone that'd do any decent alarm, fitted, for under £200 then I'd go for that, but I'm dying to go on a track day and paying £350 would kill that stone dead
 
  Cheers, 
 Ali
