Try Tiger Direct. I was just looking through it and saw some EDO ram there. I realize this sounds like a commercial or something, but I am just putting it out there for the consideration of the community. It is far easier playing DOS games on a DOS system.

Not bad, but they only seem to have 32 and 64 MB modules. Not all old motherboards may support those, and they may not be too convenient capacity-wise for some users.

There seems to be a nice variety of stock at OEMpcworld.com, with comparable prices.

A bunch of stores that carry EDO modules can be found via shopping.com.

Memory4less also has some, albeit at slightly steeper prices.

Major Memory seems to have some too, but it takes a lot of persistence to find what you're looking for.
