>From someone who bought the parts to build his first RX and TX from Radio 
Row in NYC, later bought stuff at Lafayette HQ in Jamaica, NY (in the old 
Model T Ford plant) and a year or so later saw all the WW2 Surplus at RS 
Tremont St when I was in the USN and the ship pulled into Charlestown, I 
gotta laugh at you two!

I dont shop at RS any longer unless it is for a soldering gun tip or 
something way overpriced that I just have to have at that moment. Ive even 
got an original TRS-80 up in the attic with lots of accessoriies if someone 
wants to haul it away.

Times have changed and I for one try and roll along with it as much as I 
can, even build my own leading edge PC's.
But when the mood gets me I still have plenty of old 30's thru 50's tube 
gear to fondle and get my jollies.

Even stayed up here in New England when I got out of the Navy and went to 
work for National Radio. Been up here ever since.
