I think a steel is easier, more practical, and as good. As DFP pointed out a stone grinds, a steel is more to flatten (or that is my understanding).
Any hardware store should have a steel for ~£5.
If you're near Kings Cross, there should be a hardware store round the corner from the noddle place, which is where I think I bought mine for knives and tools. Ones which have a stablising block(?) are good, because they don't scratch the surface and if you use it for tools it sits neatly in a workmate, but allows you to flip it over from the fine/rough side.
