I remember when I first discovered there were other Kirbys than the Trad, Heritage & Legends, that was about 6 years ago of course, and the Sanitronic series was one of the first "other Kirbys" I came across on ebay.com, I think it was a V.II, but it was a while ago... 
I did buy a D80 (along with a trad motor unit) in poor shape about 3 years ago from a US seller, but for whatever reason, the seller stopped communicating with me and I had to get my money refunded by ebay, so I've still been wanting one since then, and now, I have, so I'm happy, but I'll reserve the excitement for when it actually gets here... 
All it needs next is a tool set, but I'll sort that out in due course...
