Best Flashcard for DS?

I'm planning to buy a DS lite or even a DSi. Mine's been broken since 2011, but I wanted to play some games again (Pokemon Dp soundtracks on youtube got me on some nostalgic shit). I've done some research and I saw some newer stuff like R4i Gold Pro or SuperCard, but I don't have a 2/3DS so I'd guess that buying them for my DS lite would be paying extra $$. My friend suggests me a CycloDS iEvolution but idk...
