Harry,
All I can say, their distilled water must contain 80% Tanqueray no wonder it is so restricted!!--wait, I could trade my pure Humboldt rain water for Tanqueray_Good idea??

Geoff, Don't laugh . . . I was on the Hornby Railways site just now (don't ask why) and under live steam supplies they offer "Live steam water" at £4.99 per Liter. Yes, you read correctly . . . 4.99UKP!! That's H2O at about $9.68 per liter. But don't worry. . . . they won't sell to just anyone . . . as is stated in the ad . . . "Live Steam [water] is only suitable for adult collectors, not for children under 14 years old."
Regards, Harry
