Reliable UK source for MD/SNES controller chips?

[Vertigo]

Aloha.

Looking to start building circuits for MegaDrive and SNES controllers.
Does anyone know of a reliable UK source for low number orders (10 max) for the 4021 and 74157 chips?
What sort of price am I looking at as a guide? Are these chips readily available or a bit hard to get hold of?

Thanks.
