I am a 30 y old female, and would definitely be interested, as I have never had a vest - there is no way in South Africa to get access to a vest other than to buy it new (insane amount of money). I had the opportunity to try one out recently (a demo unit), so I think Hilrom does have a rep here, I would just need to source the pipes and vest which as you point out would be a whole lot easier than to get the machine itself. I am sure many people will reply to this generous offer but if they don't, and you still have it available, please PM me!! and we can take it from there and figure out how much it would cost to get it shipped etc.
*jumps up and down with excitement at the thought*
