GRD's value and

I have both the lll and lV and am thinking of selling the lll. Not sure what it is worth in the US Market as there are few if any on ebay, help would be appreciated. If anyone is interested do not hesitate to send me a back-channel message, it has about 3,000 snaps if that. Very few as I got it just before the lV came out and decide to go with that and use that when I am shooting with the GRD.
