Thanks, man...
Yeah I did look into Dynomat foam or whatever it is but it is indeed very expensive! I went around all day looking for soundproofing foam, mats, etc... I swear to God Canada has a shortage of everything. It took me 2 days to track down a friggin' Brute Ruberrmaid bin. The best thing I found that was inexpensive and safe to use was some of that pink foam like plastic stuff and the white lawn chair foam pad. Even though I left it in it's original package, (to prevent the fibers from flying around), it's still safe to use, non-toxic, does not absorb water, will not rott, will not turn yellow and is non-flamable. Now I need to find a back cover and add some more foam to it and seal that baby up!
