I'd say counterfeits are getting better with feedback from counterfeit detection web-sites (who no-longer mention the older GPX font issue)
Best to ask for the serial number, have it checked with Minelab and go have a look at it (armed with a print-out of the above data).

Maybe the handle has just been replaced. I know of a few that have broken near new.

due diligence, you may have a super bargain.
