Everybody has their own opinions on what they consider expensive and on quality. Some will say that a Glock is on the same level as a SIG and is almost half the price. Personally I respectfully disagree having owned both. This is not taking anything away from a Glock, but I just don't see them on the same level.
This is just like 1911 guys who have their favorite mfg and will tell you their Kimber is just as good as a Wilson Combat or Ed Brown. Like I said opinions will always vary.
