adaptors on ebay that are not Inpin or Xtokki

Hello Everyone

I have been looking to buy adaptors such as the Inpin (ps2 to ps3) and the Xtokki (ps2 to xbox 360) for some time.

I have put together some money to purchase adaptors for casual play and unfortunatly I have found out that the Inpin and Xtokki are not longer in production and the Xtokki site are sold out.

So after reading the thread on adaptors and finding that all of the suggested are either no longer in production or simply not available im looking for other options

I have a Namco PS1 stick and i want to use it at a small tournament on both ps3 and xbox 360.

I have seen the following items on ebay:

I know they will never be as good as the Inpin or the Xtokki but will they work?

if anyone have used them or knows of them please let me know
