Guest spawners cost $20,000, and have a 100% chance of spawning 50,000,000 guests, but if you fail, you lose $20,000! I would spawn gifts occasionally... (Gifts you ~60,000$ and ~600 diamonds) It's a guarantee that you get a reward bag every hour, but you get a gift occasionally. Reward bags give ~120,000$ and 1,000 diamonds. The super reward bag gives you ~600,000$ and ~2,800 diamonds. Wealth rains give you lots of money and diamonds as well!
