Best memory for NF7-S for $125 or less? What do you think about these?

KINGSTON HYPER-X --- KHX3200/512 REFURBED CAS - 2

and

CORSAIR XMS PC3200 C2 (actual CAS - 2.5 for my mobo)

Basically the same price, with the Hyper-X refurb holding tighter timings at same speed. Should the refurb be trusted? Does anyone know NewEgg's policy on refurb warantees (I'm looking into it)? I really appreciate the help. Please give me your opinions on these and whatever recomendations you have for my $$$ range. Thanks!

WHOA!!! This 256x2 Mushkin Level 2 PC3200 @ CAS 2.2.2 and This 512x1 Mushkin PC4000 @ CAS 3.4.4 just popped up in NewEgg refurb for 150 bucks! Are these particularly good deals? And what timings would you guess that PC4000 would run at PC3200 speeds?

This ram should be either bh-5, bh-6 or ch-5, with I personally believe the best probability being bh-5, but in any event, they would all work well with your board and it is $68 per stick, plus shipping They also have for a little less, KHXPC2700 which should have bh-6, per the attached listing, which has been mostly right, as far as I can tell.

The Mushkin linked above should also be bh-6 and would be a good choice, as well.
