cliff i'm at coventry at the moment, and whilst i also don't have anything to compare them against, i would feel more than happy to fully recommend them - great atmosphere, people, teaching and course structure
however, everyone above praising their own individual experiences just goes to show that i think you should base your final decision amongst the A-list more on what your budget allows and geographical location - it's six months out of your life and you need to enjoy it as well
thats my thoughts anyway
good luck though wherever you go - it's all good fun
