I've always bought ram from crucial and never had any issues
I'd be wary of putting 8gb in a mac that's specced to max 4gb. I looked into it for my macbook pro (from 08) and people have tried with 8gb. One guy had it working great for a month, then the computer just suddenly turned itself off and died. Another one got a flickering screen, didn't look like fun.
Going from 2 to 4 is a huge difference though, it literally made my mac workable again
