"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
Any place local so you don't have to pay shipping. I know KBs are more "mainstream" in sports places now...but i'm sure they are not that heavy. May want to call around local fitness equipment shops and try Play it Again (last I heard long ago they were going to carry their own line....no idea if that every came about).
