Thanks for the answers!
CD AGES: The Sega Dreamcast is almost non-existant here, I knew only 3 more people who owns/owned a DC through their life without counting me. So, the short answer is "nope". The most popular retro... it was the NES(It was called "Family Game" here) and the Sega Genenis, going a bit more into the future, the PlayStation 1/2.
elmagicochrisg: Maybe that's the best solution... =P
Now... is there anything to have in mind when selecting which lens to buy?
What about this one? Link!
I don't have too much luck with my international transactions, but maybe I'll give it a try. =D
