Spice racks for cabinets

There seems to be hundreds of types of spice racks. I guess this is because we are still trying to find the perfect solution to an enduring problem: how to store all those little spice bottles and jars. If a simple wall mounted traditional rack is unsuitable for whatever reason, then you may want to opt for one of the many in-cabinet or racks on the market today.
