3 button Logitech serial (ie old PCs) mouse and mouse mat (free)
Stuffed Tux (couple of quid)
A clever device that rings when you get a call and your modem is connected. Handy for single phone line houses. (Comtech IA510, cost £30 new, sell for £10)
Portable printer (can use NiCd battery pack (not supplied)), Canon BJ-10e, with PSU (cost £120ish new, but is now old and only 180dpi, so £15)
Finally, I may be seeking GnuPG key re-signing, just as soon as I work out the proper way to deal with a bad situation... I suggest avoiding auto-pgp and pgpenvelope as I'm not sure which did this to me :-(
See you there!
