[Wanted - Darwin] PLB with working battery

[Jonut]

Hi,
I'm looking to buy a second hand PLB to take thru-hiking.
Would need to have a battery with charge and at least a couple years left till expiry.
I would cover postage costs to Darwin, NT.
Let me know if you have one for sale.
Or, if you have suggestions of similar devises to use let me know, but not sure I can justify the subscription costs of a satellite device (Spot/Garmin).
Thanks,
Jo
