I'm sure you've already made your purchase of a colonic machine. But on the off - side chance this is not so, you might be interested in this:
I have a professional hydrocolonic machine for sale. It is a Transcom HC2000. It was in working condition when it was was partially disassembled and put into storage a few years ago. I bought it from a lady who had purchased it for her own use. She had used it five or six times before deciding it was too much bother do do her own colonics.
