v6 bgp peer costs?

I currently have a v4 BGP session with AS 701 and recently requested a v6 BGP session to which I was told a tunnel session will be provided (Same circuit would be better but whatever!). Towards the final stage in discussions I was told that it will cost $1500. I find this quite ridiculous and it will certainly not motivate people to move to v6 if providers put a direct price tag on it. I am going through a bandwidth reseller though so I am not sure who is trying to jack me here. Has anyone here gone through a similar experience? Thanks, Zaid
