I just ordered some OCZ DDR2 memory for a really good price after the mail-in rebate. The model number is OCZ2P800R22GK, has decent timing specifications and runs at 800 mhz. The final price after rebate is $19.49 with free shipping. Here's a link to Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227139 I figured I would mention it for those looking for a good deal on decent memory.
Definitely a good deal, but only with the rebate. OCZ is a pretty decent company so the rebate should be safe.
