I have found the 10 lb medicine ball for $17.96 at Wal-Mart and the cheapest I can find the 8 lb one is about $26 or more (Can't remember exact amount). Do you VHSers feel a 10 lb medicine ball would be way too heavy for regular Cathe video user? Just wondered if the 8 lb. ball feels great or if some of you feel 10 lb. would be fine also. I'm itching to get one but don't like the cost of the 8 lb. ball. Thanks in advance....Sami
