acekard or DSTWO for recently updated DSi XL?

From what I've read, I think acekard is the one that people prefer, right?I have an R4i, but as the stupid person as I am, I accidentally updated my DSi XL the other day, and now my R4i won't work. And I've tried everything to fix it. But I thought it was time to change anyway. I've had problems with the R4i.Which acekard should I buy (that can support the new DSi update), and where is the best place online to get them (preferably a place which accepts paypal)?Or, I was just looking at the DSTWO as well. A lot of people seem to like it too. What's your take, acekard or DSTWO? And again, where is a good place where I can purchase it?Thanks~

if you have the money, go for the supercard dstwo. if you dont, then go for acekard

I think I'm going with the DSTWO, it has a lot of great features. But question though, will it still work with my DSi XL even if I just updated it the other day?Also, if you know, from these dealers, which one would be best to buy?http://eng.supercard.sc/map/UNITED-STATES.htm

Well, I kept doing my research and DSTWO convinced me. I just purchased it off http://www.0shippingzone.com/!
