@mdalton- ultimately, you’re the one paying and have to be happy with the service you are getting. I know some buyers are price sensitive and will do set ups themselves. Finding a dealer that does it all, and discounts, isn’t so easy. I had several long term relationships during my 36+ years in NY; one was a dealer in Jersey who made house calls with gear, came to troubleshoot, whatever and his pricing was reasonable given the products involved.
If you are shopping Koetsu in the US, just be aware that some dealers will claim they are authorized but are selling gray market goods which means you won’t get any support if you want to send it back for rebuild, etc. MoFi Distribution is currently the authorized US distributor as far as I know. Good luck, I’ve gotten two stone bodies and both are fun to listen to, but different in presentation.
