Hi Dale,
I've found the new web address for the amigabest.com site:
http://amithlon.free.fr/~amigabest/english/frame_en.htm
However, none of the downloads (
http://www.chez.com/amigabest/indexeng.php3 ) are working, and the site was last updated on 3rd August 2003.
Edit: Fortunately, there's still quite a lot of useful info under the SUPPORT, COMPATIBILITY, TEST, FAQS and INSTALL tabs.
