Looking for a 7415 in any color

yes gang, I now have that white concert-5 and since it is not rare I think it would be a value-increasing idea so I'm looking for a black one but any color would work

I'll pay 100 bucks and give you my gold 7410 if that would work, or I'll sell the 7410 to anyone who wants it and pay the difference of the balance of the 7415 because a used one would work just as well as a new one .

wammiworld has them for 201.00 for reference to the cost of a used one if there is one out there
