If you feel like you wouldn't want to build one yourself, here is the one I use. My Tincture Press
I've had mine for awhile now and I LOVE it. It is so very easy to use and small enough to be able to comfortably store in my kitchen cabinets. I've linked to the large one, it was out of stock when I ordered so I had to get a smaller one, but now that I see the biggie is back in stock I'm going to order it, that's how much I love it!
