I have an R4 and i want something better...

I got an R4 a long time ago, and i have been dissappointed a lot by it, and want a new flahcart...
Well, Most;y the R4 i have has been too worn out and doesnt work well.
Should i just get another R4? or does somebody know a better flash cart to buy? also, the issue is performance, not price.

 

Get an acekard, I used to have a R4, it froze all the time. Acekard's never freeze really, and look better.

 

Awesome, Thanks. I was considering an Acekard more than the others already. Thanks for reinforcing my decision. It really helps a lot.
