Hmmm. Well there is a chance of it from just about any big time mass producer. The necks I highly doubt it very common, but bad pots, bad wiring, a stripped screwhead or some such are no more or less common than any other brand I wouldn't think. It appears to me that some of these boutique level builders that have the "budget" lines all insist on keeping them as good as they can, but never as good as the US thing. NYC Fodera, MEtro Sadowsky, Skyline Lakland, MTD Kingston, as long as these big time names are being stuck on these instruments they are going to be as good as they can be for the price for fear of damaging the name and getting people to wonder why they would drop 5000+ on the real deal some day.
That being said they are intentionally not as good as the US versions. But someone on here put it very well. A Skyline is all you will ever need, as US Lakland is all you could ever desire. Maybe a little hyperbole, but it represents the idea.
