I think like you, MoS.
I usually buy a smoked gammon joint and do it in the slow cooker for about six - eight hours. Either covered with coke, or with a good couple of handfuls of dark brown sugar in the bottom of the slow cooker, then the same patted onto the top of the joint - no liquid required - and leave it to get on with it.
I don't eat meat, but my husband, son and brother love this, either with new potatoes, peas and parsley sauce, or buttered potatoes and salad or just in sandwiches. There's always loads left to slice and pack up in the freezer for more sandwiches, or baked with sliced new potatoes, onions and white sauce.
