I am also shopping for dies. I plan on purchasing RCBS X-dies in 25-06, 270, 30-06. I believe they are around $55 per set. I think the benchrest dies are overpriced. If you seat using the quarter turn method 4 times per case with std dies and check with a runout gauge for concentricity holding a .002 tol then your good to go.
I have been told that Redding also makes a pretty good die set.
