As far as I know…
It is not more risky to buy an MK2 than a MK3. Last year I would in fact have told you that it was the other way around: given the most common fault is a laser failure, MK3 has a specific laser assembly hard to find or at crazy price at B&O when MK2 has a more usual one you can find anywhere for a couple of bucks. Since then I’ve learned that most laser failures can be solved with a deep lens cleaning (lens up/down and mirror).
In regard to other fault, I don’t remember one unit was more prone to failure than the other one and for all of them even if problems happens sometimes, its a relatively robust unit and in most cases, easily serviceable. Then the only factual parameter would be that MK3 are of course more “young” units and it may have an impact on the mechanical parts (carriage noise, door mechanism strength, discs clamps softness, etc…)
Hope this helps.
