It's not unusual for newegg to have these fast bumps in prices, especially at the beginning of the month. You can either buy one at www.tigerdirect.com or www.ewiz.com for $148 - $155 or wait for newegg to adjust their prices.
$140 is a good deal - I got one on the 'eblast' deal a few weeks ago for $130.
I think the ""$195.99"" price is a computer generated price that was set incorrectly by a programmer. New Egg has an inventory management system that bumps the price up as a declining inventory on a part number reaches a certain level.
The 'bump-up' price was just entered incorrectly - happens from time to time and results in crazy stuff like this.
