I wondered about a typo too. But ... they also have the Chaintech ZNF3-150 listed
here. And it is a different price - $160.95.
Intriguing at the minimum. Might be worth an inquiry to Axion.
I read elsewhere that the DFI NF3-250 board will be unveiled this weekend. Add to that the pictures of the retail box for the Asus NF3-250 board that was posted on Hardocp a week or so back, and it looks like maybe NF3-250 is about to pop onto the retail scene. Wishful thinking? Maybe. The fact that nVidia's rumored March 1st NF3-250 announcement didn't happen (as far as I can tell) confuses the matter a bit, although the source of that rumor (Inq) isn't always 100% accurate.
Alas, April isn't far off and there's a ton of goodies coming out then (cross fingers) for both sides of the processor fence.
edit: I sent an email inquiring about the ZNF3-250. We'll see if they respond.
