DW's are fairly common here in Texas. I see them in 22 routinely. Just graze around and you will find them.
One comment. They tend to be really cheap. DW's do not hold the original value for long. Like about the time it takes to walk to your car from the gun store is probably worth about 500$ to the original owner. Now if you are like me and buy used, great, because you can get these great guns dirt cheap. Don't be surprised if you see nearly new in the box DW's for right at $200 or there abouts. Also, the current maker out of Norwich and the older Monson guns are considered the best with the nod going to the Norwich guns. The Palmers are generally considered ones to avoid. What I am refering to is the location of the manufacturer. Look at the side plate to see where it is made.
Final thought. Bob Serva, the owner of the Norwich operation is one of the most stand up honorable guys in the shooting industry. If you buy a Norwich, and have problems he will make it right, darn near personally. I have tested the support system and can only say WOW, they made it better the right!
