Best P67 or Z68 MB from Microcenter?

I am going to microcenter tomorrow to get the 2500k for $180 and if I get a p67 or z68 MB, I will get $50 off. Can anyone recommend a good MB from the link below that is $140 or lower before the discount? I don't know if that is all the MBs they have though, I been checking the ad and the site and some of them aren't showing up on the site.

I plan to SLI in the future

I was looking at getting http://www.microcenter.com/single_product_results.phtml...

or

So it would be $180 + 70 = $250 and tax for the 2500k and MB
