Dubias are a million times easier than crickets. And they don't smell at all!
You'll need a plastic tub to house them in, a food dish, and a water dish. And some egg crates or paper towel rolls for them to hide in. If you keep them warmer they breed more prolifically so maybe a heat pad or piece of flexwatt too. Start up cost for all that would be under $30. You can get all that at Walmart and get the flex Watt online or a heat pad at a pet store.
I'd recommend getting them from Creature Addiction or BFE pets and supply.
