I made my own out of a piece of pecan wood I had in my scrap pile and a 75 mm 20cm focal point lens I bought from ebay (same thing). I also polished the glass with plastic polish, something like Mguiars auto polish would work fine, it makes a world of difference in spin times. Its not as fancy as the ones here but it works, looks nice and I made it myself!
