I tried Rx inserts in my Rudy Project Ekynox and Rydon frames. They suck. The inserts are too heavy, too small, and push the frame out too far. I had SportRx do in frame lenses and love them. I can get away with relatively inexpensive lenses in the Ekynox (<$100) but the curvature of the Rydons required a more precise grind and ran about $300. A little pricey, but very nice. Of course, these prices are on top of whatever you spend on the stock frames with plain lenses.
