I looked at the site you recommended Gadget-Asia.....very very expensive site!
I have to be honest with you, once it comes to China, Asia, Taiwan I want to run away with my wallet clinched in my hand. No disrespect to anyone but they have a reputation for selling knock off`s and I know they offer good prices but you take one hell of a chance when you deal with that part of the world. They are masters of copy but in my dealings with them my parcel either got lost, the quality was bad or it was a 100% genuine fake.
PS3 games are region free but that rule only applies when you have a full HD tv as your tv can adjust the ratio by itself to play a ntsc disc or pal. Like I said before, I looked at the UK ebay guys cause I noticed that compared to the US ebay they were far cheaper and it makes things easy for me since they play discs that are zone 2 or more known as PAL.
If I can contradict myself for a minute, I am always looking for a bargain or more specific a rock solid supplier and if this supplier is genuine and they are based in china...I will look into it but it would not be my first choice.
Regards to OEM products, I will summarize it in a quick way, has to be original in original packaging and the bonus will be a warranty but not a must. As long as we can return faulty product I will sort the customer out and the supplier can sort me out at a later stage.
So I say thank you for the effort but not on the money yet, first price will be a wholesaler or supplier in UK.
