have any people in the uk bought from myprotein.co.uk?

i have got casein protein from them, found it really chalky and horrible to taste (forgot to ask for sweetner! ) but it has bugger all in there except protein so is good from that point of view. was wondering if there are any other better alternatives?

thinking of going with protein factory or all the whey as a change, any experiences with these? is all the whey milk protein all casein or mixed with whey aswell?
