rode makes a nice screw down model that is heavy built but its expensive. i'm guessing since you use a snowball you want cheap. it looks like any mount with a 5/8 thread will fit the yeti but there are adapters even if it is 3/8 to make other models work.
i did find some other similar models, but nothing cheap
perhaps the cheapest option would be to get a cheap boom arm that you like the look of, remove the bottom clamp style connector and find a suitable flange to fit. this would let you use any of the spring style mounts you see all over amazon.ca. you might need to measure the and before buying a flange or use a spacer in some cases but should get it to work. finding a flange may be the hardest part.
the only thing i could find...
