I sold my G5 tower and I have a perfect condition 20" Apple Cinema Display sitting here with nothing to do. Gave up on the Mac; I was born a Windows user and I couldn't make the transition.
Picture is not actual unit but looks just like it!

Have to charge $25 shipping because it will be double boxed and insured. Using the UPS store and they are not cheap but do a great job. Extra shipping Alaska and Hawaii. Just cost more--sorry.
United States only! Can only insure United States deliveries.
