For anybody who is interested, the Hornady concentricity tools are now back in stock at various suppliers. I just got mine from MidSouth for $94, but I see that Wholesale Hunter has them for, IIRC, $90 and Manventure has a limited supply for $88. All of these prices are significantly below MSRP. Have not used it yet, but from what I have read, it is a great tool for pursuing accurate handloads.
