Definitive Arms does nice work. Whether or not that gun is worth the money to you, I'm not sure. It seems like VEPRs are a bit more available now, so I don't know that you'd have to drop $1k to get one.
That being said, if you were looking to suppress one, that's definitely right at the top of my list for what I'd consider in that caliber. Having the barrel rethreaded (and already check for concentricity) would be nice, and things that you'd otherwise likely be paying extra for if you were planning to put a suppressor on one. It's something I've been considering, but it's not a top priority right now.
Just kinda depends on what you want to do with the rifle. VEPRs are very nice rifles, if you haven't handled or shot one before. They're a bit heavy (they have a heavy barrel and an RPK receiver), but usually pretty accurate. Having one that's been gone over would be nice, but if you aren't suppressing it I'm not sure the value is there.
