I tried quite a few and finally found one that doesn't leak. I love, love, love it!
The brand is Homestead and I got it at Fleet Farm. The top is glass, the bottom is two pieces of plastic that screw onto the top. It's easy to clean too. I fill it upside down, carry it outside, then turn it rightside up to hang; never spills!
Mine has a hummingbird and flower etched into the glass on one side. I don't think it was any more expensive than all the other ones I had tried, and I had tried many. Someone told me that hummingbirds appreciate having something to rest their feet on while they drink, and this feeder has that too.
The flowers are a little different on mine, and I'm not sure it's the same size, but here's a link to this style feeder on Amazon:

I use a round toothpick to make sure the flowers open easily for the hummers, so they haven't had any trouble feeding out of it. I also use toothpicks when cleaning with bleach to make sure the flower openings get totally cleaned.
