In Boots there is a range called Tony Ferguson they sell a nice cup in pink or aqua for 2.49 there are vouchers for 10% off in boots at the moment. The cup makes the exante shake very well. If you fill it with water to inbetween the 250 and 300 and if poss add couple of ice cubes then shake it vigourously and it makes a nice shake with no lumps. I travel a lot and these are brill. Before I got it I couldn't work out how anyone could drink the shakes but now I really enjoy them.
