Recommended seed suppliers

I haven't bought from these but their ethics are good:-

I have bought from Pennard plants though, because they sell "odd" things that the boring mainstream retailers don't.

Thanks - they look interesting! I'll bear them in mind for autumn buying - I'll need some small winter squash for next year. Though given the huge packets I just got from Seeds of Italy, I might be able to do a seed swap instead!
