In Crucial's defense, they're ahead of the curve. Because their operation is closer to Dell's "built to order" system, they have a small lead time. As a result, their price is more in check with current market prices. This results in quick price drops like what we saw a year ago(they were well ahead in price drops than others), but it also means that they're ahead of the others in price increases. Once the current supply of cheap RAM is exhausted, everyone will be about even again.
Oh, and you're looking at the wrong prices/memory guys.😛 The $96 is the regular price of PC2100 ECC Registered memory. The usual stuff we use(and usually, all that non-pro mobos support), non-registered unbuffered, has a web price of $66.59, significantly less than the price you're worrying about.
