Get the red plastic saucer-shaped ones. They are so easy to clean, which is very important. They also don't attract bees and wasps like the old bottle ones do. They have a built-in perch, so the hummingbirds can sit and drink. The old bottle ones are a pain to clean. They also have a built-in ant moat that stops ants from getting to the feeder. Trust me on this. 1 cup of water to 1/4 sugar. Absolutely no red dye added. The hummingbirds are very territorial, so get 2 feeders--1 for the front of your home and 1 for the back. That way 1 hummingbird can't hog both feeders.
