You might try calling Smartenit on 949.429.3303 to see if they can repair or replace it but if not, there's a G2 (P2's big brother) on ebay right now with a PLM included. The price is high but you might try the 'Make an Offer' option and explain that they're asking more than the new price of $129.95 (G2 alone).
BTW, are you sure that the P2 is actually dead and not just the power supply or PLM? Any phone charger can be used as a replacement. Is the white LED lit on the PLM?
