Yes, the 4 gallon kit is what I would recommend for starting a small shop, although it\'s certainly jumping in head first
The cautious approach would be to start off with a small kit, like the 1 gallon nickel plating kit. You read the manual, plate a few objects with nickel, get a feel for the whole process. Then you\'ll be more comfortable making a serious investment.
None of our kits come with rectifiers. The manual discusses several alternative power supplies and you should probably try one of these before spending $$ on a rectifier.
