If you're hooked on a double I feel for you. I've been hooked since I handled one when I was 9 years old. Wanted one ever since. Took me a lot of years to finally get my first and can't stop now. Be careful buying and don't buy any junk. There are lots of good doubles out there and a lot of bad ones too. I bought two period bad ones and then bought a Chapuis and was happy. Its no fun to get the double you always wanted and then have to have it worked on for months. Find a good dealer to locate what you want and make sure its shoots before you buy it. Most I have dealt with will do there best to make it right. I own several now of different makes and I'LL say its worth it. Good doubles are a very good investment and loads of fun.
Good Luck in you quest!
