Scubatoys was an authorized SP dealer when they bought them. They are no longer an authorized dealer but the free parts program and warranty will still apply until the stock they purchased as an authorized dealer is sold off.
Be sure to keep your documentation that it ws purchased from an authorized delaer so that other still authorized dealers will service it. You do need to have it servcied every year (more or less, the delaer can still allow free parts if you are a month or two late) - but if you skip a year, or two or even a decade, you would just need to pay for the parts when you do eventually get it serviced to rehabilitate the free parts program. Then as long as you get it serviced every year the parts on subsequent services will again be free.
The Mk 2 is very reliable and has enough performance for recreational diving to 130 ft. It performs well in terms of inhlation effort, but it will not deliver the same quality of breathing performance as one of Scubapro's balanced first and second stage combinations.
