I had originally taken this page down as I could not find any of these left on ebay. I have found them at another site however, so here is the link:
I lost all the instructions in a hack about 2 months ago, so I am in the process of putting that back together. However, if you look closely at the site above, it is in Canada so there is a shipping fee of about $25 added if you are in the US. Just one is going to be a bit expensive. Drop me an email if you are interested in this – martan@cstone.net Dec 2020
