Who in Brisbane sells car electrics cheap??
I'm after one of those little pen size turbo timers.
Also after some good advice on a car alarm/immobilizer.
Those little pen turbo timers you are probably thinking of are the Apexi Auto Timers... they are available almost everywhere and go for about $150.
If you want to install yourself just check out some of the online shops like www.modyourcar.com.au or www.fullboost.com.au etc. etc. you could also ask supraman (Toymods sponsor) he will probably do you a good deal.
If you plan on having it installed just go to an auto elec you trust... the +/- 20 bucks you pay will be by far outweighed by having it installed by a decent trusted auto elec.
If you want an immobiliser to install yourself ask "The Witzl" as he gets the Jaycar Shadow Immobiliser pretty damned cheap.
