Ergotron LX Dual arm

I recently bought two Dell 2209W and absolutely love them.

Now I just need a dual-arm and have identified the Ergotron LX Dual arm as the perfect companion to the Dells http://www.ergotron.com/Products/tab...B/default.aspx

Anyone know what is the cheapest this can be bought for?

Model is 45-218-194 and the cheapest I can currently find it for is around £197. Anyone know where I can source this any cheaper?
