I'd say a Filco is pretty good. My only gripe with Filcos are that the MJ2 TKL doesn't have a detachable cord. You can mod it to have it, but it comes attached out of the box. This is why I sold my Filco TKL.
The Leopold is also great, and while I've never owned one, I hear the newer Leopolds have the same level of quality as Filcos.
