When you see the prices for mechanical in general, we look for a good material for a reasonable price. This is the case with the latter.
If you have a classical guitar in 5000, it might be foolish not to invest more equipment "noble", but for quality guitar that requires a quality replacement, these are mechanical fit the bill perfectly.
The "problem": the mechanical are standard and therefore valid for (almost) all the guitars, still one checks where there may be a difference, ie in distances between key mechanical. However, they have come to me slightly too long at the cylinders reels, so it took force to twist and the result, even if it is good, not perfect ...
