Lockwiki is your friend.
http://lockwiki.com/index.php/Medeco_BiLevelThe Bilevel is not a "true" Medeco in the sense that you don't have to rotate the pins...it's basically an easy six pin lock with a wide open keyway and a few security pins, plus one extra thing you have to poke to set the sidebar. The Biaxial is an order of magnitude harder.
What I'd do is pick a whole lot more locks in that Blue belt list - there are some genuinely challenging locks in there. If you really feel the need to try a Medeco, get a three pin camlock, they're a great little lock to start rotating pins on, and they're fairly common in the USA picking community so you can fairly readily trade one for something. Edit: You don't need a key to pull one of those things apart so if you can find a keyless one, go for it.
If you have any contacts with Euro or British pickers, get your hands on any of the Abus, Assa, GeGe, Kaba, or Zeiss locks on that list. Those things are all constructed ENTIRELY differently to your domestically made locks and any of them will put the fear of God into you.
