I've stated in the past, that if you found a guy willing to do it for 100 bucks, stay away from that. You will often get what you pay for! I can't stress enough how much time goes into a duck mount. Personally I charge a "good friend" 100 dollars. The artificial head alone is 20 dollars, not to mention the body form, wire, caulk etc. and most importantantly, time. The guy charging 80 bucks, after parts, is only making 10 bucks an hour! I hope he is a friend, I hope he does this as a hobby, and I hope most importantly, you have checked out his quality! Maybe you've gotten lucky and have hit all three! Wings cupped, Pete.
