I had Lansky's for years, then upgraded to the Edge Pro, and have not looked back. I need to buy the big glass plate for grinding/leveling stones, but so far I am very pleased with the control over angles, and the results. The last knife I sharpened was a Microtech Socom with S35VN blade, and it put a scary sharp edge on it with no trouble. I may look for something a little different for Kitchen knives, but it will be for quick touch-ups only. The Edge Pro is what I like best, when I want one wicked sharp.
The glass plate from them is 50 bucks, plus shipping. It has a cool ruber ring around it to keep it from slipping on the counter.
I think it is over priced, Ben Dale told me he thought it was overpriced too, but still let me order it
I ordered it, because I take my Edge Pro with me, everywhere.
That said, if you are not sharpening all over the place, you can go get a piece of .25" glass anywhere, and us it to flatten your stones. Heck, you may already have one around somewhere! You could also probably split a piece of fuel line, and glue it around th edge, just like they do.
I also think a peice of granite would do the trick, just the same. Find a local flooring guy, he probably has a piece he may give you for just a few bucks, or less.
