I would like to assemble an Avalon clone but assume that someone is doing a bulk order of boards. Since the avalon unit is tested and working it seems to be the safest route.
Let me know if you are doing so or looking to do the same. If no one else is, maybe we could put together a joint effort to get the economies of scale needed.

P.S. My apologies for posting this here, this is the only place I can post at this time.
There is a thread here somewhere with someone that has created a board clone (IIRC it's a cloned board but with the Avalon chip). Past that, I'm not aware of any cloning going on currently.
