If you're in the USA it's very unlikely that you will be paying custom taxes on it ordering from Keyboardco directly. Plus, as stated if you find them on Amazon they're anywhere from $140-$170 depending on which model you want. The stock in Amazon is somewhat limited right now but if you wait till mid-June there will be an inventory update with loads of good options (including a Filco with mx reds!).
And alternatively, you can find a used or mint condition in the classified forums for as low as $120 shipped. I sold mine recently for around that price.
Edit: and yes they're worth it lol! Filcos are at the top of list in terms of quality. While they won't be miles ahead of your leopold, I still prefer Filcos.
