As a former Ljutic owner I think the reason for the rapid upfront depreciation is the fact that they aren't widely known, and more people don't understand what terrific, massively built, quality guns they are. They don't produce an annual volume anywhere's close to K or P guns, so they aren't a dime a dozen on the gun rack, therefore they aren't a household name. But then again, when was the last time you heard of a Ljutic barrel blowing up or trigger breaking?
Because they aren't as well known as other makes, their re-sale value is affected -- instead of fighting this phenomenon, take advantage of it. As someone else stated, there are terrific deals on this list for used Ljutics, often in excellent condition. If you've shot one, it points well, and you break targets better than with whatever you are currently shooting, give one a try.
Lots of gun for the money -- just my opinion.
