I started getting some random BSOD lately. I tested my sticks with memtest, and it seems that 2 of my sticks are bad

.
Since I bought from someone on the forum, RMA is not a question. (My intention isn't to flame the guy who sold me the ram, and I won't name it!).
So, I will have to shop for a new kit. I was thinking about selling my 2x1GB Ballistix (the 2 good stick) and buying 2x2GB kit (preferably PC2-8000/8500). Any suggection on the kit to order ?
I heard some good things about some redlines (I can PM on NCIX for 95$ after a 20$ MIR). Any other suggestion?
