PowerBook 12.1 1.5ghz RAM question..

Hi all...just looking for compatible RAM types and I'm having trouble determining which brands are compatible outside of APPLE's own versions.
Any help is much appreciated......

Other World Computing offers really good prices on Mac upgrades. Here's a link for RAM upgrades for the 12 inch PowerBook 1.5 GHz.

1.5 GHz 12" Powerbook RAM Upgrades

I've bought RAM from OWC in the past, and I have had great service.

I always use Dealram.com.

Have upgraded ram on four systems over the years, all through that site.

Thanks for the help, I'll be sure to check those out!
