Well
I only dealt with digitexpert.
I bought a legit 1.8" 2GB FMP, for 45 AUD(including shipping)
It wasn't hacked, I checked it visually and though format.
Altough there was no box, It was OK.
The only problem is the battery, It lasts only about 2 hours.
Other than that no problems.
As I have not dealt with others...
And a INTERESTING discovery.
There was also a invocie included from a different company(

The ebay sellers probably use dropshipping.
The price on the invoice was 9 EURO!!!
