lovely_day,
You could purchase one Yacdol & just have an antiseptic wipe cloth handy to clean it before doing the face if you do the feet first. They're extremely easy to clean. That would keep it very inexpensive for you.
I only have the Bong Mu Shon, and while I'm getting very creative with it, and doing a good full body routine with it, I can't see it at all for use on the face. Too large a stone.
Hope you get one because its fantastic!
P.S. Does anyone have any creative 'moves' they want to share?
