Perhaps not much, although I was surprised that they even had 7805's and 
7812's. There was a variable regulator (most likely the LM317 that Dave 
mentioned) - but I think they wanted close to $5 for that, and I had a 
feeling that put it more into "wait until I'm next ordering components 
online" territory.

Yes, it's mainly the DIY circuit fabrication/repair things that I want to 
keep an eye on - their breadboards were rather expensive, but some of the 
tools and bare PCBs might be worth getting in a few weeks if the prices 
drop a little more.

I might load up on D-sub connectors and DIL IC sockets, too.
