Thanks again so much for all your support, it really helps to pad the heartache.
Next month I am getting this incubator:

It's local and very popular with breeders and schools, it's a forced-air model which holds 42 eggs, comes with an automatic egg turner and digital monitor for temp & humidity. The whole thing is about $240 (canadian funds).
My breeder recommended it so I'm sure it'll be great, the store said the customers all loved it
Poor broody hen looks lost in the coop today, clucking and wandering aimlessly around, I haven't seen her eat but I'm sure she'll eventually click back into the groove. At least she wasn't sitting on any eggs when I went in this morning, that's a positive sign!
What a HUGE learning experience this has been.
