Rather than buy the Pardner and have to buy a recoil pad, just get the Topper 20, it already has it. Keep the money in your pocket and spend a little time shopping; you arent trying to get it for a hunting season anyway and can wait for what you want at the price you like.
Remember, too, that you have to buy shells; get them maybe now on sale. I suggest 20ga. 2 3/4", 7/8 oz. of #7 1/2 and #6. Around here I can get them for about $6/bx.
You say you want to target shoot so maybe go down to the local 'Rod & Gun Club' on trap night; watch, and listen a lot; just dont let the high rollers buffalo you about wanting to start with a cheap gun. There was an 'old' guy who used to show up every year for the money shoot with an old ratty single shot that he had used for everything for years. He would win or place; always going home with more money than he came with. Drove the high rollers with their multi-thousand dollar trap guns crazy. He was nice too.
