I listen to a lot of Stoner: try 1000mods, Truckfighters, some Black Space Riders (they're the least stoner of the bunch, the earlier albums are the most stoner, and the most recent is probably the least, but I really like where they're going, so like their most recent stuff the best), High on Fire, Monster Magnet, and some of this:
Kyuss is of course the godfathers of Stoner. Desert Sessions (with a rolling cast of musicians) is also pretty great for classic Stoner.
