Toilets: Best performers available from Major Manufacturers
Most suppliers can order these models
In general I like the 1 gallon per flush (gpf) over the dual flush. The dual flushes on the market currently are .8 gpf low and 1.6 gpf high. The combined average is the same as a 1 gpf toilet over 4 flushes. If there is any question as whether the end user is going to use the high more then the low, I would go with the 1 gpf.

Bricor
Bricor manufactures the most efficient shower head and areaotors on the market today. They are used by the US military in Iraq. The only caveat for these is that they require a set water pressure which you need to find out and buy the appropriate model. Low pressure rural well systems may not work.
