No, but I think that you want me to.
Bill, I say, "If you want it, go for it! You won't be disappointed." You have several great cameras that a V3 would certainly compliment. It should easily fit into your lineup. For me, it's the ideal travel camera. I love the compact design and solid production. It works for me. Ask yourself why you want it. If you can justify the purchase, do it. My entire V3 kit fits in a small camera bag. There are many times when I don't want to lug around my D810, especially when I'm out on vacation or a business trip. On the other hand, some days, I prefer my D810 for those special times, when I really want that special shot. I hope that helps, and don't hesitate to ask me more.
I just thought of something . . . You already have a V1. I'd sell it or gift it out to a loved one, which is what I did with my V2. I can't see a need for both, unless you want to keep it as a part of your collection, and that's OK, too. If it makes you happy, pursue it. The goal is life --which is short -- liberty and the PURSUIT of happiness.
