I am afraid no Scooby will do that, they all lose money like its gone out of fashion, but an unmolested P1 will IMHO lose alot less than most of you dont mod it. They are quick enough anyway in standard guise.
Speak to Paul or Jenni about one. Jenni hasnt had hers for too long so it would be good to get first impressions from her.
What is your budget by the way??
