I have a single faucet tower that I am selling. it is older, but not in too bad of shape. you will need new tubing, and it will need a bit of cleaning, but it appears to be functional. I have never used it, just bought a BM23, and I am upgrading to a double.
20 bucks, flat rate box, I can send pics via text or e-mail if desired.
let me know
thanks
Don
