Turbopad to usb adapters?

[batmreload]

Please forgive me if this is in the wrong section. I'm looking to adapt a Turbopad to usb for usage in emulators.

Ive seen a couple, recently this one came up, does anyone have any experience with it? I'm interested in it mainly because i have 2 turbopads that are missing their wires and I'd like to try to build it inside the gamepad itself:

Ive read that some of the adapters don't handle the turbo functions well, and would like some opinions on what others have tried.

The other two adapters I've found are either the USB RetroPad adapter:

Or the blissbox:

Can anyone shed light on how well these have worked for them, particularly the turbo functions?

In addation, can someone point me to a wiring diagram for the internal connector of the Turbopads? Both are different revisions, one marked VG-1001 and the other NEC PWD-624.

Thanks!

Answered my question, at least as to the internal header inside the turbopads:

Matches 1-9 (left to right, printed on PCB) with 9 being the DIN shield. Thought it was laid out differently. 

So, has anyone has positive experiences in regard to the above mentioned USB adapters?
