It has been quite a while since i found anything worth buying on ebay. Usually it is broken or overpriced before shipping. I found a relatively local seller who was selling a bunch of older powerbooks and other items.

I am now the owner of a Powerbook Duo 280c with microdock, 2300c with ultradock, and a Newton 120 with accessories.

Total cost = $115CDN including shipping

I also found a stack of 50 sticks of SDRAM for about 15$ which will come in handy when I refurbish some older iMacs.

All in all, a very good, but expensive day.
