Hi Mike, welcome. Your knife selection sounds great to me. I have the 210mm Artifex in AEB-L steel and I love it. Sharpens up wonderfully easy and scary sharp. I got mine with the stock factory edge and it was OK. A few minutes at the Edge Pro and it was awesome!
As far as the sharpener goes, I had an Apex to begin with now I have a Pro model. To me hands down it was worth the extra money. Are you even a little obsessive in nature to begin with? If so you might as well just go to the Pro version to start.
As far as the WE goes, it does look like a gerat machine, but the availability of after market stuff for the EP just made the deal go to the EP for me. I have the Shapton Glass stones sans the 30 k stone for mine and they rock. Could not be happier, and the service I have gotten from Mark and Sue at CKTG has been just awesome.
