Just to let the people on the forum know:

Staples currently has the SanDisk 128 Meg SD card on sale for $39.99. It's originally $89.99 with a $30.00 instant discount and then a $20.00 mail in rebate.

I picked mine up yesterday for my new Treo 90 and it's working great (with MSMount and Launcher X).
