I just bought one, and I went with a medium tree that I think will be just perfect for you! It's about 3 to 5 feet tall, and I'd be happy to sell it to you for anywhere from $50 to $100. Some gardeners sell them in different sizes, so you can choose the one that works best for you. The large one is about $100 or more, and it grows to be about 6 feet or taller.
