[sllug-members]: DDS Waveform Generator

[Michael K. Elwood]

For low/hobbyist quantities on an enormous range of parts, Digikey is 
your best friend. www.digikey.com

Some others you might check out:

www.mouser.com
www.newark.com
www.alliedelec.com

There are some local electrical supply stores, but they tend not to 
stock anything but the most basic/common stuff:

Standard Supply (~3400 South and main)
Ra-elco (the closest description I have for these guys is an electronics 
flea market -- you'd have to see it to understand)

As a long shot, you might try your local Radio Shack. :-)

Hope this helps. Good luck with your project.
