Thanks to a timely alert @LightBulbFun , I was able to purchase a Kanga PowerBook on Ebay a little while ago. The one I bought is 250mhz and has the RAM maxed at 160mb. The price was quite reasonable, especially given what these generally bring on Ebay. I'm incredibly excited about this-the Kanga was the only G-series laptop I didn't own an example of, and one of the few G-series Macs I didn't have(I now only lack an iMac G5 and an Xserve G4). Full report when it arrives.
