I wouldn't go near those adapters on eBay, you still need a programmer to read and NAND memory is not supported by many programmers, even the ones that do support it only use the old 528/2112 page devices.
So you would only find yourself able to read the really old type 48 Pin NAND. Modern ones are very complex, some need voltage adjustment to get a clean read, then when you have NAND dump its not over there, you need to find and correct using ECC codes and find the XOR keys in order for it to even start to make sense, then you have to work out the block ordering.
NAND recovery is not for the faint-hearted. Look at this page. This descibes a very simple layout.
