Brian,

Yeah, I actually called them and they said "maybe we'll get more". I got 
an email the next daying that the part was so obsolete that they 
wouldn't be stocking anymore :(

> Ramjet still has them.

Can you give us a URL, please?

I also know that SaTech allegedly sells them:

http://www.satech.com/

They have 32, 64, and 128MB SIMMS for the Qube:

I have ordered a 128MB SIMM but have not yet received it from FedEx. 
They have a horrible (non-existent) package tracking, so I don't even 
know if they've shipped it, yet. :(
