If you are talking to the local guy who is "very well known" and "does really good work" and his price is $455I have to ask; would you go with someone unknown who mayor may not do good work for $300? I promise you $155 5 years from nowwill not be felt in the least bit,but a really good mount will be enjoyed every day just asa bad mountis a kick in the teeth every time you look at it.
