Candle centerpieces?

I need your help ladies, can you post pics of different candle centerpieces...I can't find anything I like - I must be looking in the wrong places! I am looking for something a bit more elaborate but am open to all ideas! This has to be a less expensive way to go then floral centerpieces right? . Also if anyone knows of a place where they could be rented (the stands, whatever type they maybe be) that would be awesome! I certainly don't need a whole bunch of candle stands around.
