Please don't take it the wrong way.
I am just saying that I notice in your sig that you have PC2 6400 Ballistix tracer's already, so I was just kinda wondering why you would ask what kind of ram to get when you already have decent ram - especially since you noted they are D9's. And you may not be a RAM guru but from posts I've seen you make you sure seem to be a decent PC guru, so that's all i was getting at, no harm intended!
(basically your question kinda threw me for a loop)
I'm pretty sure the tracer's are just like regular crucial ballistix's except have extra led's and perhaps better heatspreaders? someone will have to confirm that.
So i recommend Crucial ballistix. I even
had 4x1gb's on my 64-bit Vista system and they were stable at 1:1 with a 400 FSB OC.
G.skill's are good too.
And for $150 you can score 4x1gb's with some of the rebates still going on.
