[sdiy] Parts sources

[Dave Leith]

Thanks for all the suggestions. I'd still prefer to go with the metal
clip if possible as it is serviceable and allows good contact with the
thermistor. I'm pretty positive I won't be ordering 5000 though :-)  I
like the idea of the cable tie but not sure how to include the rather
large thermistor with the 2 transistors either with the tie or with
the heat shrink. It seems a bit awkward..But now I have some things to
try.

Thanks again
