Reading this thread I think what has become clearer and clearer is that it really is horses for courses. ESPA suits me; it's clean, it's quiet, it's friendly and well supervised; it doesn't play house music and it has nice soap (I'm a real girl). I try to go for an hour 4 times a week; I just arrive, plug myself into my i-Pod (Nirvana or the Stones) and get on with my programme. What's not to like (for me)?
