I've used a Sears/Mossberg 500 for about 40 years without a complaint. I liked it well enough to buy another one in 20 ga a few years ago. The Remington 870 is another that a lot of people like. The Browning and Ithaca guns are good.
I suppose it depends on what you want, and how much you want to spend.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
