And now you can see why aluminum might not be such a bad alternative.
Prices on aluminum haven't gone up as much as for copper (in proportion).
Granted, it's a bit trickier to bond than copper (I don't think thermite
will work with aluminum like it does with copper <grin>).
Some may not realize what you are grinning about. To illustrate, consider
the solid rocket boosters used on the space shuttle are fueled with a
mixture of ammonium perchlorate and powdered aluminum suspended in an epoxy
resin.

There is *speculation* that copper prices will fall next year, so you might
be able to do some options trading to get tomorrows price today (plus a
premium). (aluminum prices also fell yesterday) But hey..
are we commodity speculators or antenna builders.
That speculation has a lot to do with reduction in troops in Iraq. Right
now it's a crap shoot IMO.
