I do not own a laser system at present, but I personally would not purchase a laser system from anyone who did not have spare parts on the shelf, and who did not offer board level repairs, spare parts, honor the factory warranty, and offer telephone support after the warranty period.
My reasoning: I have been in the electronics business 40 years, and expect the same standards of service from a Chinese or other laser manufacturer that I offered to my customers these many years. Anything less than the above, takes advantage of the customers. Without support and spare parts reasonably priced, they will not be loyal or repeat customers. Also, they will tell all their friends the experiences they have had (good and bad) in dealings with the company. In nearly all situations, bad experiences travel by word of mouth much faster than good experiences.
Just my 2 cents.
