I LOVE cast iron cooking in every respect. Regular everyday cooking, BBQ/Grilling, camping, etc... Main meals, appetizers, sides, desserts. Anything you can cook in any other type of pan or pot I do in cast iron and love almost everything about it.
I have both old and new pans and dutch ovens all in daily use. If you want "easy" buy the pre-seasoned Lodge-Logic line of cookware. I have had "decent" luck with it but prefer to season my own usually. BUY THROUGH AMAZON WITH THE LINK ON THIS SITE !!!!
I, though, prefer finding old pans at flea markets and/or garage sales or in the internets and cleaning them up and re-seasoning them myself. Takes a little work but not too hard by any means. Clean them up with 4-aught steel wool (this removes the grease and rust and surface blemishes), heat your grill up to blazing hot and stick the pan directly in the coals for a bit to burn off the old seasoning and crud that is left (can also do in the self-clean cycle of the oven too if you wish). At this point you should have raw metal so be careful to not get it wet or you get rust quickly (easily removed but still). Then simply season again and it is like brand new. You can do this over and over and over.
USE THEM A LOT. The more you use them and care for them properly (NO soap EVER - any stubborn burnt on stuff that won't come out with just water you can use a little bit of coarse salt and water in like a paste!!!!!) the more seasoned they become. I have several that are as close to non-stick as you can get without buying non-stick.
Eh - sorry - I ramble, but you really cannot go wrong with cast iron. If cared for properly it will be something you can will to the kids and they to theirs and they to theirs....!!!!
