A member on here - Footy Shorts Shane sells them. I've got one and reckon they're pretty good. No huge contracts etc - just a cheapie prepaid sim with a long life is best.

Tim, we have a new model in production now. I think you will like it
Without turning this into a showroom thread
a couple of new features include, GPS-A 3G module plus SIRF GPS chipset, (not one or the other, both
) Optional remote for alarm activation, vehicle alarm adaptability, digital input for an alarm activation (reed switch on a fridge box, tool box etc, or door on caravan/crossover etc).
But the best bit, video monitoring. With alarm activation, the unit will video call the authorised user, providing video evidence of the person driving your stolen vehicle away, or those who entered your caravan/crossover etc unlawfully.
Same deal as the current model, no monthly fees, only prepaid credit.
Shane.
