Welcome from a fellow wet weather sufferer. Where abouts in the UK are you based?

Check out cgarsltd.co.uk for humidors, they have regular offers and sometimes do seconds, a search on google products also returns a few at a reasonable price. Thing is that if you are not looking for something to display a tupperdor or coolidor is a hell of a lot cheaper.

Distilled water can be got at Halfords or B&Q. B&Q or similar also sell hygrometers pretty cheap, but they are generally quite large.

Tupperware or similar can be got at most department stores.

There are plenty of beads available on ebay but I am pretty sure that I have some spare and could send you enough for a small container.

I use cigarone.com for most of my purchasing and they are a damn lot cheaper than buying in the UK.
