Another sub company you might wan to look at is Elemental Designs and Epic, both out of the States and made in house so they should be Duty/Tax free.
I am wondering if you want real deep earth shaking LFE or smooth bass as the EP800 will move the earth but 2 Ep500 or 600's will still shake pretty good but allow for smoother bass response through out the room.
If you really want to stay budget conscious I would stay with the outlet for all speakers, but if want a little more eye candy and are willing to pay the difference go for the Vassallo series, nothing is quite as nice as real wood veneer
