In addition to the previous answers, which I completely agree with, I would also recommend to look at 1) where the distributors of the resin are located (which also affects the price tag), and 2) whether there is any customer support that you can call. I have worked with vinyl ester, which requires a careful selection of typically toxic catalysts.
