I've been using a modified DK-22 with a DK-17m epoxied into it, with a DK-19 eye cup for the last few months. I like it, but I can't really see the entire frame -- the corners get cut. It is a bit too much magnification. I just ordered the parts for this set up so I can compare them. I'll post back once I get a chance to try this non-magnified setup.
