V-1,
I stopped by on my way to visit the inlaws in IL. The show room is actually a small warehouse, with racks of shelving and catalogue items out where you can walk up and down the isles and pick things out. This can be useful if you're interested in patterned, stabilized wood, etc.. They do have some grinders on display also. It's nice to compare them (visually at least) if you're in the market.
There is also a small display of hand made knives and some other stuff.
The folks were pleasant. Mr. Koval wasn't there when I came by. They had a show that weekend, which meant that a lot of their stock was packed up. I'd check with them before making the trip, but you'll probably find it worthwhile.
As far as prices, they are not the most expensive, but most items can probably be found at least somewhat cheaper if you're willing to shop around.
Hope this helps.
