Text-To-Speech Fans

Curious how many people here frequently use text-to-speech. It was rather horrible years ago, but I find it quite usable now. I enjoy audiobooks, but sometimes they just are not available for the books I want to read, so I often turn to text-to-speech. I mostly use Google Books version, but have used Amazon, Moon+, and Fbreader for audio.
Anyone else frequently use TTS?
