There are practically endless options these days, and your budget and taste are your only limitations. Locally, big box stores like Lowe's and Home Depot have large selections, and you can check their websites before you shop. Local Plumbing supply stores will also have a large selection. Also, try Amazon or Ebay, or manufacturer's sites like Kohler or Moen. Personally, I'd start with a Habitat for Humanity's Re-Store to see what they have!
