Depends on what you want to do with it. A lot of shooting needs a more robust scope, occasional shooting not. Any scope will allow you to shoot as far as you want, adjustable ones just make the target definition at longer distances clearer and your trembling and movement with breathing very noticeable.

A 38/3-6 should be more than sufficient. I have bought only one new scope all the rest have been pre owned and used. Never had a problem.
