I like the Morrisons Eat Smart Lincolnshire sausages. Kind of spicy but good enough to pass for a sausage and I can't stand quorn so these do the trick. They are a syn each on red/EE. (or half, must check!!)
Weight Watchers Pork sausages are good too, I like these in a casserole or on their own, half a syn each on red/EE.
