Ok I did the same as you though way back in 2001.
What you need to get is a step-down converter. You can get these at Lik-Sang.com for like 10bucks. You can buy them at home too, but in Europe theyll charge you like 100€ for it.
Then you need an NTSC compatible TV.
To get games Id recommend dvdboxoffice.com, they have free shipping and prices around 48€ for game. They take long to ship though (2 weeks, sometimes 3). They offer courier shipping for 15bucks.
Also great it National Console Support.
http://www.ncsx.com/They have similar prices but always charge shipping, the cheapest shipping is 9bucks, but you get your game within 4-5 days max (if you live relatively convinient. Great for games you have to have fast. (Metroid Prime, Zelda etc).
I think the broadband adapters work everywhere. This is a question for Rick.
