doreen,
thank you for the reply.
Unfortunatly i can't find either of them where i live (i even tried the GNC and SuperWalmart in my area). in fact, no one even seems to know what i'm talking about when i ask about them.
i know you can order them off the net but i imagine the shipping costs of something so heavy would be pretty high.
oh well, bummer. thought they would be fun to experiment with .
