Congressional Term Limits

At the Tea Party Coalition Forum Tuesday Senatorial Candidate Pat Toomey stated that he did not run for his Representative seat because he promised he would serve only (I think) 3 terms. Any thoughts on term limits being set as law?

One potential result being nonprofessional, non-serving for life politicians, opening up the field to more potential candidates. Or, would it dilute the talent pool and bring a more nonprofessional, unproductive stock of legislators to office? What would be reasonable term limits for both Houses? Two terms for Senators, four terms for Representatives. Perhaps non-consecutive terms?

Another thought: Would any Congressman/woman have the political courage to propose and pursue a paycut for Congress? A reduction in the benefits they receive? Health benefits for life? You have to be kidding me. Who works for who here?

Any thoughts or opinions?
