The Real Seed Company are great and have great ethics (all open-pollinated) though the range is small.
Chiltern Seeds have an enormous range including lots of heritage open-pollinated varieties (F1 Hybrids are clearly marked) and give, in my opinion, lots of seeds for the money and are not too expensive.
I have ordered from both of the above companies, both UK based, and they've been fantastic.
My friend always uses Chase Organics and I have their catalogue being sent but I haven't ordered from them yet. May not ever really need to if my seed-saving goes according to plan this year. Actually, if it goes well I may have seeds to swap for next year.
