Gary,
It's gonna be tight to stay under $1k with a 20g SKB on the open market these days. But, it could happen. Model 100s are extractor guns from what I've seen. 200E is an ejector gun as is the 280E. You picked a good gun to get your money's worth. Also, the BSS 20g can be found for $1500 ish. They are excellent as well.
