I just bought some 10-46 nickel plated. I would have also bought some 80/20 12-56 (Bluegrass), but they were ... out of stock. The best (bulk) pricing at webstrings.com ($2.74 per set) is comparable to what I used to get a D'Addario 10-pack for at Amazon (subscription). It's a much better deal now that D'Ad has raised prices. But, if as some say, the cause is rising material costs, then that gap should sadly narrow sooner or later. A couple years ago, Maury's was selling Martin acoustic strings for $1.00 per pack. I bought a TON of 'em, but I wish I'd bought more. I'm running out.
