I use my Otter Box - Defender Series phone protector as a dock. A set of USB powered speakers and a USB hub to split the HTCs power pack to power both the phone and the speakers. Sure, not real pretty, but the speakers cost me $10, the USB hub I had lying around. The Otter Box was $60 ish, but I use it as a protector, not just a dock. Maybe on the weekend I'll fabricate a more permanent type of dock and document it for you wonderful people.
