Oracle is an option (especially for converting CentOS without reinstalling), but it has become stunningly more expensive.
There used to be a $99/yr "support in name only" option, with no ability to file service requests (community discussion boards only). The basic level of support was $500/yr.
It now appears that basic support is $1,200/yr. Of course, ISO downloads and yum support are still free, but the support contract is now much more expensive.
Oracle also still offers free KSplice kernel updates for Ubuntu, but it appears that Fedora support was removed.
