I disagree.
A repair technician (like any other professional) will put a price on their time, and low priced equipment may not sustain those revenues.
Low end equipment may often take MORE time to repair than Hi End equipment, either due to their age, or quality of internal construction.
Hence they simply decline repair of low cost products.
I don't see this as snobish.... Of course to each their own perspective .... but calling someone you have never met or interacted with, or understand their business policy, "a show off" or "snob" or even worse, an "***hole!" is WAY out of line.
