Anthony,
If you're an ebayer, you may be able to pick up the British version of the Hasegawa Apache pretty cheap. I've gotten three off of there for no more than $20US each. The British WAH-64D version is the exact same thing, just has British and Dutch decals, but the kit is a US bird. None of the special mods on the foreign birds are included.
As far as the better of the two aforementioned kits, the Italeri is the only one you can build a production machine from. The Academy kit is the prototype and needs extensive modification and a completely new cockpit to be accurate.
