It's simple supply & demand (well okay it's a bit more than that but).......so many are convinced they HAVE to have the latest & greatest as soon as it comes out..(see Ipad, Ipod etc...)
This is completely true of the used market, particularly in regard to ebay. I often wonder just how large and rabid the photography market is. I believe 100% that if I listed one million used 85mm 1.8's and one million used 5D mkII's they would all sell.


Just buy it when it's on sale/refurbed/used and tell her how much money you saved by buying it then as opposed to later. Usually works for them, why not try turning the tables.*
