If you only want ARM cores, then this will be the least expensive: http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143452239825 <http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143452239825>
Don’t count on the same level of support because they don’t have a Robert Nelson on their team.
