I'm off of using Ebay now, not because of Paypal but due to a browser exploit
that can properly certificate a bogus site of the main domain.

I'll go CompUSA barebones build, AMD CPU, 2Gig RAM, GeForce Nvida AGP,
case, power supply and 320 or 500 Gig W.D. hard drive.
All for 200 U.S. plus a CPU fan additional.
CompUSA islocal to me.

I've not a computer T.V. card but a set top Apex 250

Not really, at these freaquencies the minute microvol currents travel 
on the outside of wire.
The crossover means the uppermost and bottom elements wiring isn't direct 
between the middle two elements but rather the wire connecting the 
middle two go to opposite side elements top and bottom.

 JB> Update: Those "crossovers" are electrical connections to six or so
 JB> elements I saw in one of the vids, I take it?

4 elements each side, middle two on either side connected to each other,
top and bottom elements are connected to the middle two however
to opposite sides. 
Thus the wiring crosses for the top and bottom opposing elements.

I yanked that tagline too but paraphrased it a bit to my liking.
