One thing you want to keep in mind is that there are two types of patch panels: Soldered and jacked, and there are three types of normalling selection: Switched, soldered or "flipped".
The soldered ones usually are ment for permanent installation. You buy cables, and solder teh cables between the patch panel close to your mixer and the jacks in your sound room and to your racks. You also often solder the normalizing.
That's perfect for permanent installation, of course, no unessecary costly jacks that may fall out, and no internal switches that can rust.
However, if your studio is in your bedroom and in constant change, you probably don't want to unscrew your rack and pull out the soldering machine each time you bought some new gear, just to connect it up. And if you (like me) move your stuff around pretty darn often, because you can't decide how to organize your cramped studio, then you don't want to buy new cabling each time either. In that case you want jacked patch bays, with jacks both front AND back. These come in all varieties of normalling selection, but the common ones are the 'flipped' where you flip a circuit board inside, or 'switched' where you select with a switch.
More expensive, but less work.
The Behringer ones are jacked with a switch. The Switch unfortunately is not on the front or back-panel, meaning that if you have it in a rack, you need to unrack it if you want to change the normalization.
Here are some more jacked patchbays. That top one PHB-256 has front-panel selection of the normalling. It's just 'almost' balanced though, which is weird.

I don't have ANY idea of the quality of these though, I haven't used them.
