Save your money, don't buy the Bergara. Criterion, Jim@NSS(though I believe he uses Criterion blanks, still GTG either way), McGowan and Pac-Nor. McRee was also selling barrels and nuts, not sure if they still are. A lotta folks on here will give you flack for doing it, but ignore em. Their reasons are strictly aesthetics or they think it's sacriledge, but in reality, they're probably just butthurt that they paid someone $300+ to chamber and install it.
Savages have a very unusual feel to the bolt, kind of clicky and ratchety, but the upside is you can service em with simple hand tools. Remingtons have a better feeling bolt(just my opinion obviously), arguably better lockup, and more aftermarket support; but are not easily serviceable without a lathe.
If you can take the good without inheriting the bad and you're in need of a barrel swap, there's very little reason not to go with this setup; again, unless, of course, you're a snob.
Best of luck, hope you find what you're looking for.
EDIT: You didn't mention whether or not you already have the rifle or what make it is, but if you don't and have a decent budget, you can also look at the Shilen DGR/DGV custom actions. It's a 700 footprint so it'll accept most 700 stocks but they also utilize a barrel nut system so it's a nice high end option for you if you're starting from scratch.
