It's weird, for such a small country we seem to have a lot of competition between dealers and techs.
Roland themselves have just pulled out of NZ and the master dealership has changed hands. So, a big shakeup going on. All of a sudden the guys who were doing the servicing are going freelance, with great prices.
What happened before was a tech would travel to our area and service maybe 5 machines over a couple of days. Each customer would get a charge for travel and accommodation. It was not the costs split between the customers but a full charge for each customer. Basically they were gouging 5 times their travel costs.
Now with the freelancers they will divide the costs between the number of jobs. Servicing has fallen from around NZ$650 to about NZ$400.
Everyones madly scrambling to pick up the market share of the old master dealer so the deals are awesome.
At the same time you have to acknowledge that if you want the warranty to stay in place then Roland and their agents have you by the balls to a certain extent and you just have to suck it up and pass the extra costs on to your customers.
Since they play that way you should have no loyalty except to yourself and play these guys off against each other whenever the opportunity presents its self. Give what you get.
