Nespresso Vertuo Machines - Krups vs Magimix?

Hi all

Been looking at these for awhile and wondered if any knew of any difference between the two?
Some reviews and websites state the magimix had a 1.8l tank vs the 1.2l on krups (but i've also seen the magimix at 1.2l as well!)

Cheapest seems to be the red magimix on currys/amazon @ £59.99 or krups is £64.99 for black

thanks!
