Topband: K2ZJ Beverage Box Replacement?

[wd3q@erols.com (Eric Rosenberg)]

N3OC set up some EWEs in my DC backyard for this past weekend's contest 
using his ZJ boxes.  Very nice, especially with the ground rod 
attachment.

I understand 'ZJ is gone, so the question is whether anyone has picked 
up the ball and producing something with a similar physical design (the 
preamp versions worked well, that is until I zapped one).

Thanks in advance.
