I personally don't think they're worth it. The TV chefs and chefesses always have them but a) they don't buy them and b) they puts masses of other flavours into them. St Nigella soaks it for ages in a buckets bull of spices etc.. Last year we discovered the Bernard Matthews factory shop, a turkey crown for about a tenner, tasted as good as much dearer ones with all the extra flavours in a Christmas meal. We're doing Boxing Day, beef and a ham, last year's Christmas cake for later, forgot to cut it last year!
