I'd like to make the move to all-grain, but it's fairly equipment-intensive. I see combination mash tuns and brew kettles. Are these a solution? Can I use the kettle for mashing, then transfer to another container, clean this one out, and re-use it for a brew kettle? That sort of seems like asking for hot-side aeration and hassle?
If they're not reusable, they just seem like an expensive replacement for a 10 gallon Igloo cooler with false bottom, right?
