Buying used beer distributor for homebar

I and my wife are searching a used Bottoms Up beer dispenser, because we would like to use it in our home for partys.
I saw the video on youtube and i think it is a great invention!
We are searching also a used one if possible, because it would be cheaper for us i think.
Someone knows where i could find one with a cheaper price to ship abroad?
Thank you in advance.
