Check out realseeds.co.uk if you are in the UK (or even if not they may still post abroad). Their catalogue is made up of open-pollinated varieties for saving your own seed from. They even have some open source designs for seed-saving hardware and are very based. In fact most of the veg currently growing in my garden is fourth or fifth generation from seed I bought from them is and is adapting to my local conditions.
