One advantage of the Road Morph not mentioned so far is that it has a short flexible hose that connects the pump to the valve stem, rather like a scaled down floor pump. With the hose, it is almost impossible to break off the valve stem while you are trying to get the last few psi. Breaking the valve stem is all too easy with a conventional frame or mini-pump.
Highly recommended.
Alternative: A mini-pump to get the first 20psi or so, then a CO2 inflator. Even more highly recommended.
