r4 card.. which to buy?

I had a R4i v1.4 card and a Dsi sistem, i updated the Dsi and then my card didn’t work and i was told i can’t change that now so i’m going to buy a new one..
i want to use it to download games into my dsi and whatever.. which one should i buy? im kinda confused
I want to try the games before i buy them.. i get my money from babysitting.. can’t afford to buy lots of games that are going to suck, so i just see which ones i like to buy..
