In Sep/Oct when I get back to the states Iím going to be selling a Manfrotto Super Pro mkII 161MK2B Tripod *No head*. Iíve never sold anything on ebay before and I donít have access to ebay in Afghanistan to see how much they are selling for. This is brand new, still has the tags on it and has only been setup up 1 time. The only thing it doesnít have is the original box. Itís $550.00 on Amazon. Do you think setting a minimum of $400.00 is reasonable? How does the whole ďBuy NowĒ work?
