I messaged Nathan, the ebay guy, and asked to confirm whether the camera he is selling is ntsc or pal. His response was this:
"no scams here, ntsc for sure, ships today or tomorrow the latest, thanks, nathan"
That's a bit more reassuring but it's just still his word. *sigh*
I think nathan has better track record than time2envy (the same people as Broadway and ibuydigital). if you google time2envy you will see lots of complaints on other forums. I also googled masonjersey. No issues so far. One example here.
