If it has VPM unlocked, that'll bump the price up some. If you're not really clear on whether it's an EXT model, that would explain people asking $850 for a used Petrel 1 (though that seems low for an EXT). But generally speaking, $650 is a pretty good price for a Petrel 1 - I was selling Predators for ~$750 back when the Petrel 1 came out at $950.
