[sdiy] Potentiometer Source

[Scott]

Hello,
I've got another parts sourcing question.  So, just like the surplus jacks I asked about the other day, I used to be able to find little alpha potentiometers for about $.50 each at a couple of different surplus stores.  Both seem to be out.  It's been a couple of years, so I guess prices have risen a little, but just like the jacks, the best price I can find now is several times what I was paying.  
So, does anyone know where to get a bunch of inexpensive pots?  I need about 100 100k, and 50 50k.

It looks like this hobby is a lot more expensive than it used to be a couple of years ago! ? !  I should have finished these modules back then!

Thanks!
