I think it pays to buy in new seed every so often, just to keep things fresh. There is always the possibility of perpetuating weakness by saving the same things year after year (incest! Gasp!) Having said that, I always save the seed of my favourite tomatoes because they are quite expensive to buy, if you can find them.
The only thing necessary for the triumph of evil is for good men to do nothing.
