Macmall.com seems to have some previous generation configurations. However, the Matte screen machines are similarly priced with Apple clearance but the glossy machines are priced at a premium. It could be that they are indeed BTO and you can't get that kind with glossy screen anymore because Apple won't go to the trouble of adjusting a generic system...?
I would buy the new 2.4ghz Penryn, but I'm pulling my hair out thinking about that L2 cache changing backwards from 4mb to 3mb!
