I'm pricing this stuff too. Crucial has more of a discount for first-time buyers using crucial.com/webpromo (15%) minus another 5% ebates but it collects tax in about half the states. Shipping is at cost $5.50
before shipping/tax/ebates
PC100 CL2: $77
PC133 CL3: $85
PC133 CL2: $89
I have a BH6 which apparently cannot take advantage of PC133 and I doubt my next mainboard will use SDRAM so I would be more inclined to get PC100 but both 100 and 133 is $69 from Core which pretty much matches the PC100 price direct from Crucial. So, the question is which PC133 CL is Core selling? They do not specify.
Oh yeah, I could not find it with a search, just use the specials link then memory etc.
