WTB: Clamshell/Dual USB iBook

I'm interested in picking up a clamshell or Dual USB iBook. I'd prefer something in decent shape with no missing external parts (e.g. optical drive cover, key caps), but hard drive capacity and lack of AirPort card are no big deal. It would need to come with an AC adapter, but if the battery is dead that's OK. The only catch is that I don't have a ton to spend. Shoot me a PM if you have one to offer. Thanks!
