Robinsons sell something called a "munch station", like a corner hay rack but fitted at floor level, then if you want you can fit a corner manger in the top . Think its about £80 though!
I've got munch stations, marvellous invention IMO, yes, expensive, but I'm sure I've saved the cost of them in wasted feed and hay. They are so easy to fill and have completely cured my youngster from kicking his feed over! Can't recommend them enough
