Rohl makes a beautiful product. Generally, the quality of their brass and finishes is better, hence the higher price. But my advice is to make sure whatever you buy has a ceramic valve that won't degrade as quickly over time. Sometimes, big box stores will take the body of a higher priced faucet and replace the ceramic valve with a plastic one to keep the price lower. So it may look the same, but it often doesn't have the same performance. And if you're getting a pull-down, make sure the retraction mechanism will snap into place. Agree, too, you should buy from a reputable plumbing supplier. If there's a product defect or some other problem, they can work with the manufacturer to troubleshoot.
