If these are for home use only, there's a way to get your games set up with Insider Connect without having the full hardware kit. Perhaps this has been posted here already so I apologize if I'm duplicating info. Check this Pinside post:
I've done this with my Iron Maiden. Just needed a wireless dongle and a memory card. I add friends to my Home Team using one of my games that has the scanner and they will appear on Maiden after I power cycle it. It's all pretty simple to set up.
