[sdiy] parts watch

[Ian Fritz]

Hi all --

PN4391  --  Mouser allowed me to order small quantities of these in TO92, 
at $0.21 ea.  Not as good as advertised in the catalog, but still a good 
price.  They're on back order, though.

KT/KTY  sensors from Infineon are now available at Digi-Key  (I believe 
they were unavailable from the common US suppliers for a while).  Prices 
range from about $0.4 to $6. depending on package and tolerance.
