What's best? M3 Real or R4 + EZFlash 3-in-1 or other?

Hey everyone. I was just looking into buying a cart or combination that plays both ds games and gba games. Not counting the memory card, I'm looking to spend max $60, maybe $70. These are 2 solutions I'm looking at:

m3 Real w/gba expansion
r4 w/EZFlash 3-in-1

Any opinions as to which would be better and where to buy them? Is there another solution that's cheap and better?

Thanks.

 

I would go for the m3 real combo. I have had very good results with m3 products.
