I recently picked up a pretty decent Ithaca SKB Model 100 20ga for $850. They remain my nominee if you're talking best gun for the money under $1,000. They've been around for over 50 years now and have a solid track record. Miroku-made Charles Daly is another good choice under $1,000. Mark's Zephyr Woodlander might well get you the most bang for your buck at $500. Made by V. Sarasqueta, a good Spanish maker.
