Even simpler to do it yourself if you have an EFIS. Mine is simply two quarter-inch aluminum tubes held together by some fiberglass that are plumbed into my Dynon D100. Pitot tube should face into the wind directly, AOA tube is below the pitot and cut at about a 45-degree angle (so that if you were climbing at 45 degrees, the opening would be directly into the wind). Exact angle doesn't matter, as you can calibrate it through the Dynon software. Cost was essentially zero as I had scrap pieces of tubing laying around.
Caveat: I don't know if/how this might work with other EFISes but worked perfectly with my D100.
