hi where can i find a FREESTANDING PUNCH BAG FRAME that will hold a 40kg punch bag because i have no where to put a bag indoors. Also are these bags any good? I dont want to waste my money on these if they wont last. http://www.boxfituk.com/boxing-punch-bags/heavy-duty-pu-daddy-bag/prod_935.html http://www.boxfituk.com/boxing-punch-bags/heavy-duty-pu-body-punch-bag/prod_934.html Thanks for the help
