In u.s., you can write it off as a bizness expense. it'll save you twenty to forty % of the purchase (in the long run).
I came to this forum because it announced somewhere that it was a primary resource and forum for SMIL I guess that attests to the fact that SMIL has yet to take off as a flash alternative because their is not that much discussion about it.
I've been having trouble finding a SMIL authoring package. Some seem obsolete and to have disappeared. Others are requiring me to compile and build them on unix. I still haven't tried any Windows options.
But if you don't mind doing code, SMIL is a free option. Browsers are getting better at supporting it (?maybe).
