As one of my friends at collage got one of these a while ago, hes been raving about it ever since! So i decided to try and buy one, as they cost about the same as a normal game and allow you to play mp3s, videos, pictures and, cough, ROMS...
Sadly, i cant find them in stock anywhere! The alternatives seem to have build quality issues, unreliability or more complex software (than the R4).
Wait... they're out of stock.... oh well... But yeah, what you're looking for is the M3 Real. The Perfect bundle also allows compatibility with GBA games and homebrew.
I can also attest to Kickgaming that I've had pretty good service from them. No problems, ever... And it comes from Canada, so I don't have to pay tax. But yeah, check the site, they'll probably get more M3 Reals in stock in a week or two if you don't want to test your luck with other services.
Best luck man.
Oh... if you're really a picky buyer, you might also want to consider the CycloDS, it's probably the other "Best" cart out there.
I think im going to go for a CycloDS, whilst build quality doesnt seem to be as praised as the R4, the UI and Cyclops Team Support are very very highly praised! Its also bit a pain in the arse to get hold of THanks for suggesting it BeAuMaN!
Well, I got a M3 Real and so far, it works as it should be. And it supports SDHC too. Even though R4DS and M3 Real are from the same manufacturer, I don't understand why the new R4DS flash card does not support SDHC and their packages do not include Slot-2 Expansion pack.
The above site is out of stock and based in the US
Me and a few freinds have bought these cards from www.consolextras.net they are UK based and seem to know their stuff and offer some great deals, I was after a few cards so I contacted them at their website and he put a deal on the website for me.
