where to buy decent ram

I have heard people talking about the poor quality ram at Fry's and I think I
would have to agree that their ram is not so great. Seems stable at 100MHz or
lower bus Freq's and Below 700 MHz processors. But when the RAM clocks get
pushed they become unstable.

So I guess what I was wondering is where I can get 2 256 MB RAM sticks that
are halfway decent? I need a place in Phoenix as I don't have a CC to make
web purchases.
