WTB: Dimmer/relay pack with chaser or audio flash capability

[Craven Sound]

I'm looking for a cheap relay pack that will flash lights using either an audio input or built in microphone; basically an automated light controller. I'll likely be selling it at the end of the year, because I'm doing a few favors and don't want to spend a lot. Let me know if you have anything, or would be willing to do some sort of trade for other audio gear.
