Hi Jpod!
My husband and I are going to Japan over xmas/new year (again... 3rd year out of 4), and we were excited to learn that foreigners can now purchase SUICA cards.
There is even a NEX/SUICA combination that gives you good value on your journey to/from Narita as well as a SUICA card to a certain level of credit.
I would love it if you would do a lesson or feature on SUICA cards, where they can be used, how to use them, etc.
The SUICA website actually has a 35 page user guide on how to use the card, but it would be interesting to get firsthand information from those of you who live there!
