I started into partial mash and later all grain using BIAB on the stove. I never liked handling a heavy bag of very hot and wet grain, even with help it was easy to make a bit of a mess. Last year I went the cooler mash tun direction and haven't looked back. Lot less mess, when the mash is done, just cart the cooler (with the hot and wet grain safely inside) down to the compost pile and dump. I have a hose that I hook up to the stationary tub in the garage and give it a good hosing out with hot water, then leave it drain and dry. Less mess, less fuss in my opinion.
