I can recommend my breed too, we have Zwartbles, they are naturally quite tame breed and much more biddable than our xbred sheep that have a bit of Welsh in them! Zwartbles are quite striking to look at with their black fleeces and white markings and although the show sheep are on the large size, there are plenty that are a smaller size too. Some of them can be really tame and seem to like to be around people I think this may be due to their origins as a dual purpose dairy sheep, they also halter train quite easily and stay in their fields too!
It may be worth looking at all the breeds at the larger agriculture shows, you can usually ask people questions about their sheep and can decide which breeds you most like.
