    I recently sold a full piece of nice B&W stock that lists for $200. That price is irrelevant since they don't sell to individuals anyway. One of the big name ham stores advertised a similar piece for $300!
    I wasn't getting any wiggles from the ham community and it wound up going for $50 to some guy who wanted it for his daughter's school project. I hated to see it go like that and I suspect it was not the appropriate coil for whatever she was doing (Tesla coil?) and tried to talk him out of it to no avail.
    Oh well.

    ice maker copper line makes wonderful high power inductors / loading coils.
    i use the material for a home brew inverted L coil that helps to resonate a 160M (and also 80M) inverted L. Far cheaper and easier than using capacitors. No moving parts in this, cost is $8 or so.

    The stuff is easy to work with and works very well.
