Is $700 a good price for a new 12 BVSS?

I'm having a hard time deciding on what I want to do. I sold an AR for $900 with the intention of replacing it with another .223. I also want to build a 6br and I don't know what I should do first. If $700 is a good price on the BVSS, it may make my decision easier. I would rather have a 1:7 twist, but I'm wondering it the 1:9 twist of the BVSS will stabilize a 77g Matchking?

Another route I could go is buy a Shilen barrel for my existing .223 Stevens, and restock it and probably have a better shooter than the BVSS for a couple hundred cheaper, but then I won't have an action to build the 6BR on. Decisions ...Decisions.
