Questions about Broadband Adapters

[whiteninja]

Alrighty, I've got a few questions about the BBA for the GC.

• I was looking around on eBay and I saw several BBA, but some of them had different things after "DOL" for example "DOL-105" and there was a "DOL-1A-something-or-other." Are there different types of BBA's that you need for GC's made in different countries, or is there just one generic one?
  
• The BBA looks just like a smal, black box, but I thought you were supposed to hook it up to your computer, and there are never any cables shown with it.
  
• I currently have horrid dial-up, but will soon get Verizon DSL; I can use that to go online, right? I know some ISP's don't let you get online.
  
• Is there anyplace other than eBay that you can get them cheaply?

With a little luck, maybe I can get online in a month or two.
