Ah so they do make one!
Good find.
But im with C&S, that is going to end up being close to a grand by the time it arrives and you pay tax etc - and that makes a K Pro much more inviting. It would have to be very cheap to persuade me, much as I love J's stuff. They are normally an exchange item too.
C&S is right too, they have hundreds of off the shelf maps which will be a safe and rougly matching map for your mods.
