Alternatives to GeoHex in the UK

Why but expensive GeoHex tiles in UK?

Gallia make scenic tiles in high impact polystrene foam at competitive
prices
They may not be a HEX based system (the tiles are square) but they are
*A lot* 
cheaper & have a large range of terrain variery. Quality is very good.
Gallia 
are in all the UK wargames Mags. Highly recommended. (I've also made my
own and 
its not worth the hassle.)
