I've posted this before -- but I happened to notice that the components are
on sale at Cabela's. Here are the details:

and the stuff you need --- the zodi heater has been discontinued -- hence
the low price --- it's now 44.99 --- regular price was $99 and I paid $59

The Zodi Stovetop Heater:

The shower enclosure is on sale for $50

For those of you who question my motives for this post, I just want to make
it clear that I, sadly, do not own Cabela's :-)

Cheers,
Doug
