I have a used OceansMotion SuperSquirt for sale. I experimented with it using eductors and stuff a few years ago. I used it for about three months, it has a very small amount of surface rust on it, but nothing that affects anything.
I have the equivalent of a version #2 drum, but the drum is actually custom made. It started off as a version nothing drum, I then used a dremel to enlarge/make an opening. I also have another drum that one could use to make into whatever they want.
New it is $259 USD.
I would like $165 for mine plus shipping.
