As others have mentioned, FKS bindings are great. I ride them myself. However, they do have their downsides.
1.) They are no longer being produced, and are therefore hard to find. Be ready to pay top dollar for them.
2.) Above being said, replacement parts can also be difficult to find or expensive to buy.
3.) Their brakes can be a pain in the ass. You will probably need to bend them to get them to fit the waist of your skis. also, if you need to replace the brakes, you will need to buy a whole new baseplate assembly, which costs $40. Kind of expensive.
If you are willing to deal with the aforementioned cons, FKS bindings will be awesome.
of course, all of what i just said may be irrelevant to you if you only need maybe a junior binding or something lower performance.
