I have the Agena SWA 10 15 and 20mm set for my refractor. I liked em so much I doubled them up for Bino use. At f8 they are pretty much perfect to 90% out and in the bino's which is what I got them for are clean all the way to the edge, when used with the 1.6X OCA. At US $125 for the three or $250 for the six, in my case, they are excellent value, at the time I got them the exchange rate was in the Aussie favor! GSO Superviews are also good as bino pairs but I had trouble with ghosting in the 15mm in the bino's which the AA 15 doesn't suffer from...
I think Andrews sell the same ones at $79 each, at last look. The only minus is tight eye relief in the 10mm, much like ER in a plossl.
