Hope you get on OK with your propagator, Reg. Personally I've never found the need for one.
Whatever you do, don't fall into the trap that a lot of folk do.
Only use it for stuff that really needs heat, peppers, tomatoes etc. (definitely not brassicas!) and don't leave the seedlings in once germinated, they will get leggy & drawn.
Sorry if I'm teaching Granny to suck eggs, but I'm just thinking about all the threads posted this year from disappointed people who had done just that.
