has anyone else tried Lloyd Walkers latest tweak

Wow! only $325 for a quartz crystal that probably cost the better part of a dollar. Seems reasonable, but wait, why don't we just go to a mineral or gem shop/show and buy a bunch of different size crystals for peanuts and then try different ones and use the one that works best. It may be $300 of work or intellectual property to have it pre-sorted for us and Lloyd is a most enterprizing guy... I think I'll opt for DIY on this one. Thanks for the tips Almarg and Perditty.

Perditty, you should go for the pretty light green peridot crystal. :)

Yea it's the old joke about fixing the pentagon computer buy hitting it with a rubber hammer, for hitting it $2 for knowing where $9998

Maybe geoff and lloyd can partner up and market a rose colored crystal. New company:

Pink Fraud

Al, interesting theory. It's also possible the crystal does no such thing and is simply a very efficient vibration absorber. If it were absorbing RFI/EMI I imagine the crystal would have to attract the offending electromagnetic fields like a magnet. No?
