While that was once the case, more and more these engines exhibit quite good quality out of the box. I have examined the reed cage on all my DLE engines, and only the ones bought 4 - 5 years ago needed any attention and even those were not that bad. Sadly, the reputation for poor quality remains when 95% plus of the issues were resolved long ago.
