There are a lot of homemade shot makers running around the world, the secret is in the drippers most of all. If I had the time and space I would have built one, twice the size of the littleton, but the price and the fact that I just had to plug it in was a good selling feature. Oh and I got it when we had a stronger dollar
You will probably spend the 400.00 building one and rebuilding it to make it work.
