I still have yet to find any simple steel water bottles that can be used to boil water in, but here are some aluminum ones...they're both aluminum and have anti-leaching linings inside the walls. The highest rated Chinese import for steel water bottles is Klean Kanteen.

Liberty Bottleworks

Both brands are becoming easier to find at local brick & mortar stores.
