www.soundproofing.org (and www.auralex.com and probably a bunch of other acoustical/sound sites) have some GREAT info but sometimes their product prices are inflated.
I'm not sure of the rules here on bashing companies so here's a couple examples of what's available out there - you can do your own price comparisons to sites like the ones mentioned above:
Acoustical Caulk
www.roancorp.com - Tremco acoustical sealant for under $8 a tube (large 29 oz. tube).
Mineral wool insulation (very dense - seems good for soundproofing)
local Thermafiber distributor (contact www.thermafiber.com) - 3" thick mineral fiber - $.27/sq. ft. in 16"x48" batts
Acoustical foam (various kinds)
www.foambymail.com - shipping costs are still a killer.
Anyway - shop around! Some of the soundproofing can be done for a lot less than you might think. I almost gave up on doing much of it until I found some of the sites above.
