I'm looking for a solution to select 1 of many AV inputs. I'm thinking somewhere from 16-24 inputs. The only thing I can come up with is a 3 deck rotary switch with like 24 contacts but anything I can find are custom orders that are $100 plus. I'm not interested in spending more than $50. The most I can find for an actual input selector is 8 inputs. If I can't find another solution than I'll get 2 of those boxes. But I would like a more elegant solution if I can afford it. Any suggestions are appreciated. Thanks
