Oxymoron. Potfillers need to be better engineered than regular faucets as there is no drain under them to get rid of the drips or floods. None that meet that requirement are cheap.

We installed this one in our temporary kitchen. It works fine, nothing fancy. We are building and I wanted to see how I liked having one. It doesn't leak (so far), and it seems pretty sturdy.

Sometimes you can find good deals on ebay - refurbished or maybe someone bought the wrong one and can't return it, etc.

I would caution against Danze. We've had a series of bad experiences with them. Which is strange, considering that they are just a tarted up Delta from a different factory.
