Honestly, I find a tub of Elmlea regular or light double cream works for me. It's oil-based so similar to the fakiness of American coffee creamers. I only use a small amount of the Elmlea, much less than if I had Coffeemate or half and half.
I cannot stand plain milk in coffee so this works well...for home use. I stick to lattes or tea when I'm out for a hot beverage.
