yes I do know what Im talking about its a prewired ranco big woop go on the big auction site see how much they are new then do the -ing on a used product see the problem on this site is everyone still thinks you can get full value of a used item when they payed msrp on it at a LFS then the best quote is it was barly used for only for a half a year soon as you open the box that product has lost money just like when you drive a car off the lot it has lost money since your dealing with electronics its even worse cause everyone knows how undependable they are
