That depends on the framework. Some are free i.e. Codebook, others cost around $500-$600.00. My preference, as I've said many times, is VFE. Check out there website at f1tech.com for prices. As for support, you can get phone support, or free support via the web - here and on their site. They have been around a long time, have many users, a somewhat annual user conference and are moving forward with the technology.
