Which Flash Cart??

Hello everyone wonder if you can give me a little bit of advice here. I have a supercard one which obviously i use for my nds games, and I would like to get a slot 2 cart so I can play gba games, can anyone give suggestions as to which is the best to get, must admit I'd like one that sits as flush as possible into my ndsl. Thanks :-*

M3 Real?

Ez-flashv? Go to http://www.gbatemp.net/ then reviews. It has heaps of Slot 1 and Slot 2 reviews. That might help you out.

M3 Real is supposed to be good from what I've heard, I have no first-hand experience though.

Thanks everyone for your help, I'll check these out and I'll let you know when I finally make a decision ::)
