If you can afford one then it is the way to go. And then when you open your web store, all you have to do is put more plastic in it! LOL
You can do a lot of baits with it, but I may suggest an alternative heat source for tinkering around with recipes. When I tinker, I do it with 4 oz of plastic. The presto will do that, but it may be easier in a smaller pot/pan/pyrex. Just a thought.
