Affordable??!! What will it be needed for. Small CC. 4" mid sized for trail or home use or a hunting revolver. Today not much is affordable new . I guess a DA/SA is wanted. Look around for a used but cared for revolver. Buy warn off is fine just not rusted. An L frame 586/ 686 s&W, ruger any, dan wesson 15-2 series would be a favorate of mine as barels can be changed a used prices are still low enough to make them a worthy buy. Maybe an eaa windicator 2 or 4" barrel for well under 300 dollars new will serve your needs. .
