iBook - How much is my iBook worth?

Hi all... I will shortly be selling the following iBook... need an idea of price 'for the UK'

- G4 iBook 12 inch: screen clean, unmarked, no dead pixels

- Wireless extreme and Bluetooth ready

- 40GB HD, DVDR/CDRW

- 1.33MHZ: last incarnation of the 12 inch with the fastest processor

- All original packaging, accessories, software discs, cables etc. included as when new

- Upgraded to 1GB RAM

- Top quality padded, pocketed carry case by 'incase'

- Adobe CS2 will be left on it (discs not supplied)

- Always used with a mouse so trackerpad area clean/unworn - Apple wired Mighty Mouse included

- Used as a 'desktop' home machine - never taken outside and always powered by mains so battery life excellent

- Battery NOT subject to Apple exchnage programme - serial number confirms this

- A very clean, fully working example: minor - and I do mean minor - marks to exterior casing... mostly to the underneath... 'top' is very clean

Thanks!
