If all you need is 250FSB then I would go for Crucial ballistix Pc3200. They will ran 2.5-2-2-5 at 250FSB with 2.8volts or so. Tccd is more flexible though so if you think you might need something like 270FSB, go for those.
Unfortunately the later Ballistix PC3200 rated 2-3-2-5 won't do this. There's that Sweden guy who posted similar results here recently but that's old news based on sticks no longer available in the U.S. He probably got one of the first batch of sticks in Europe due to slower moving stock.
Any of the new ram out can do 250, 1:1, but what's important is the timings. The Ballistix is still your best bet for anything close to -2-2- timings.
People don't realize how slow 2.5-3-3-6 is. I recently did a 3DMark2001 comparison bench on my NF7-S. Listen up, as this is rare since all you see is guys proclaiming high fsb >230 on NF2 boards. Apparently this is based on Memtest, a Sandra Mem screenie, or Prime. But where's the proof of the pudding: 3DMark scores? I find the boards are 2D stable but won't pass all four 3DMarks there, particularly 3DMark2000 and 3DMark2005, not with 2x512 and CPC Enabled anyway.
3DMark2001 scores:
221, 2-2-2-11 (XMS3500)=19191
235, 2.5-3-3-6 (TCCD)=18781
This is 2x512, and with CPC ENABLED. The scores speak for themselves
. Everybody speculates about the damaging effect of CPC Disabled (hmmm, any 3DMark scores to back that up?), but here you can see the damaging effect of slow CAS settings, CPC being equal.
