Shanon - do you like the DC24? I bought one on impulse a couple of weeks after they first came out, I thought it was so cute! I do NOT like the 'tool', though!
Karl - The DC02 came in the following variations:
Standard (grey/yellow)
Absolute (grey/yellow/purple)
Clear (transparent blue/transparent green/yellow)
De Stijl (red/yellow/purple)
Recyclone (green/yellow/grey)
Antarctica Solo (white/light blue)
The DC01 came in:
Standard (grey/yellow)
Absolute (grey/yellow purple)
Antarctica Solo (grey/blue)
Blue (grey/blue)
De Stijl (red/yellow/purple)
They also made the DC04 in the De Stijl colour-scheme, but I'm not sure how many were made. The De Stijl models come up on eBay all the time - I don't actually like the colour scheme, or I would have bought a set already! It's getting harder to find them in nice condition, with all their original, colour-matching parts, so perhaps I should invest in some now!
