Need a good deal on bags! I played alittle too much!

I am just asking everyone if they know where to get a good deal on some slam specialty bags. finally pissed off at firestone for making weak bags. didn't they think when they made them that someone would be fuckin around and shooting 400+ psi to the bag? any bags that can handle some good pressure but slams are preferred. i'll put up a pic of the bag on my profile when i get off my lazy ass and rip the mfer off the truck. it is so beautiful!
