Finding a normal looking kitchen faucet with side spray and filter
You may want to try at a local hardware store as opposed to going off to the big chain box stores. My local hardware store has a few catalogs that show many styles of faucets for kitchen sinks - including a lot of "normal" looking ones. 

There are also a number of online sites including www.faucet.com although I have not always been convinced that their prices are all that great.
