So I officially can't find my PowerBook G4 power adpater...and I don't want to pay $80 for a new adapter, especially since I'm planning on selling the PowerBook soon if the new form factors for the MacBooks materialize. Any suggestions on places to look for them? I've seen the cheapo ones on eBay for like $30. Has anyone tried those? Does anyone have a link to somewhere much cheaper than Apple sells them?
