Are http://www.harborfreight.com/cpi/cta...temnumber=8826 these the clamps so many people use? I remember a couple people saying how cheap they were, but got the job done. If these arent, can I get a link to the right ones? thanks

P.S. Will I need any other size clamps to do my first biuld (Tiger 60) or will these alone suffice?
