Negative Voltage Regulators

does anyone have a good local source for negative voltage regulators? i'm after some TO-3 package 15V and 18V voltage regulators... seems pretty dumb but i'm struggling to find a supplier for the -15 and -18 (even the +18 actually). checked RS, jaycar, x-on, farnell... i thought these were pretty standard but maybe not?
part numbers would be L7815/7915 and L7818/7918 or similar (or LM320/340 in the old language).
actually I only need one of each, so if anyone has some lying around...
cheers, wez

Not local, but ebay kills all others for cheapness on bits like that..

thanks mike.... how ridiculous that it might be easier to import such a trivial part from bulgaria or the netherlands! surely not.

That's the way it is with small electronics components these days. Silly, I know, but what can you do?

I have one but not the other, from memory the 320? I'll be back there tomorrow.

this happy little fella does either voltage, with 2 extra resistors....
