Where is the PS2 network adapter?

[megakevinexe]

I have Metal Gear Solid 3: Subsistence, and since the game has an online service, I need to know where to find the PS2 network adapter so I can play online! I'm having lots of trouble finding it, and I can't find it even in the obvious game stores, like GameStop, Toysrus, also RadioShack, etc. Do you guys know where to find that thing? I really need to find it! Please?

You can buy a loose used Network Adapter at any GameStop/EB stores...they usually have a good amount lying around.

There's always eBay. Just make sure you pick a decent seller with good feedback.
