It depends on what you want out of the gun and the $$$ you have to get said gun---

Merkel and Chapuis are cost effective from 7-8K & up, Searcy for 10K+,used.They certainly get the job done.

Double that for a new Heym, & others but you get better attention to details,better balance, and more features on the DR.

Past that you can cruise the websites selling used "best quality" Doubles as noted in previous threads or jump right in it and order a new DR.

Its all great fun, and a joy to shoot such rifles.They are generally worth the $$$!!

Now if I could justify the cost of a new 450/400 Heym with scope mounts, great wood, etc---

I know I couldn't stand the $$cost of a full featured H&H comissioned similarly unless I won the lottery, but I would surely love to have/shoot one.
