What you ask for is somewhat of a paradox. I order to be frugal (or, as I understand it, cheap) a revolver has to be chambered in either .38 Special or .357 Magnum (which also uses .38 Special). This enables you to use the cheapest available revolver ammuniton that can be easily obtained. However, if it is great power that you desire, then the .357mag may not be enough for you. Larger calibers cost more to shoot, and this coupled with recoil may dissuade you from shooting much. If by frugal you mean 'cheap to pruchase' either buy used or buy Ruger, or both.
In addition to that, do you prefer a single-action model or double action?
Finally, there is one more point. The following are acceptable terms for a revolver: wheelgun, sixgun, roundgun or hogleg. Anything else is punish by a beating with a sack or doorknobs
