Found one on CL that was attached to a Danby kegerator for $160 bucks! Sold the keg and tap that came with it for $50 bucks so I'm only into this CO2 tank, regulator and kegerator for $110 bucks. But now I have to fill up another stinking kegerator with beer. Life sucks.

If you find any free ones, let me know!
I think you were lucky to stumble on one free one.
They go for between $80 and $90 most places that sell them.
Your best bet is to check craigslist regularly for a cheap one.
Let's see if I keep this updated!
