Epoxy suppliers in the UK

[SamFoster]

epoxy resin seems to be rather more expensive in the UK than in the USA, there also seems to be more brands in the US. I was wondering if anyone knows of any suppliers of cheap epoxy in the UK?, I was also wondering if it is possible to use polyester instead, I'm aware that it is not as strong as epoxy but will this really matter on a 10 foot rowing boat?

Poly is not as easy and forgiving to work with as epoxy. Plus it stinks to high-heaven.
