Most folks on this board are partial to the Silverpuppy and the Silvergen. It is just a bit more than the one you are looking at, but there are features that make a great quality silver. For example I know the Silvergen has a stir feature (not sure about the puppy - it may too), that helps the silver not to clump. This creates finer particles and a nice clear silver.
I had a less expensive version for years and finally got a Silvergen. I'm so happy I did. It's an excellent machine, and creates a strong silver that is consistently clear. My old one was creating weak silver, or if I made it stronger it was yellow which is not as good.
