PS3 Sixaxis/Wireless Adaptors?

[Muramasa]

So I'm planning on a project that may or may not involve Scott Pilgrim in the future and I need to make wireless arcade controls for the PS3. I've looked up how to do this, and apparently, the only way to do this wirelessly is to A) solder to the controller (which is highly unrecommended for novices i.e. me) or B) use an adapter called the Shinjn Sixaxis Adapter. It works similarly to an IPac, so it's not very hard to work. However, I came to learn that Shinjn is no longer making these. I did find a site called Shadaloo, an arcade parts supplier, that says they have some in stock, however, I could not find out if they were credible and up to date or if they actually had any in stock. So I basically have three questions:

1. Is Shadaloo credible/are there any other ways to obtain the Shinjn adapter?
2. Are there any other Sixaxis adapters out there to use?
3. If I absolutely must, are there any good guides to soldering onto the Sixaxis controller?

Any help is greatly appreciated!

@HaRuMaN Thanks! Can't believe I didn't find that on my own.
