Ok, I'm back... just couldn't stand it when I have only a little to say. :)
You could buy something to hold the bacon flat when you're frying it (it can curl even in the microwave, I've found!), but simpler and cheaper because you don't have to buy anything extra: Lightly dust the bacon strips with flour before frying. The fat will fry out of it, and the flour will lightly crust and make the bacon hold its shape. It tastes great, too!
