Hi Longwood,
I have a 3G 30GB that I am thinking about selling. I really don't use much more than about 8-9GB so I am switching to a mini (going to use my playlists more efficiently on the mini). My 3G is in nearly new condition, very, very few marks, always kept in the case. Comes with the dock, firewire cable, a/c adapter, original earbuds, original case and I believe the remote is still in the original box too. Also I have the iTrip and EarJams for it. The EarJams snap onto the earbuds and greatly improve the sound of the earbuds. Great battery life as I use it every day and dock it at night and never do I run out of battery power. With all the accessories I'm looking at around $275 + shipping. One other thing that may be of value to you...I'm an independent Apple consultant and owner of our firm here in central Florida. The iPod has always been used only in the most professional environments and never abused or tampered with. I am extremely sensitive aabout all our machines, particularly something more mobile like the iPod so every measure to keep it pristine has been taken.
Let me know if you are interested!
