The Blue Live Work Loft is my favorite.
I have time to check quickly maybe once every hour or so and I want to collect as much money as possibile with each visit =) 220 per hour. 264 if tipped! Pays for itself in a few weeks. Then it's all profit. Soon you won't be wasting clicks on anything that pays less than 200 coins. Unless it's a community structure which just gives you more clicks to click another 200+.
