I have had work done that is on the lower to middle end of the spectrum on price and most of that particular taxidermist's work is good, but not great A blacktail and a bear rug and euro elk. I actually think he is the most cost effective place on earth to do a modified Euro if you like his style with it.
I however have had some work done by a slightly higher priced taxidermist, roughly 20% more expensive, and the work is all of 20% better if not 40% better. It isn't until someone points out the differences in the less expensive taxidermists work that I begin to take notice. Now that I know what I am looking for and my own little pet peaves I am a little bit more critical. I also notice that the higher quality work holds its integrity for many more years than the average work.
