1. Poison Dart Rokkaku by Premier
Still in production, a google search will turn up a number of retailers that stock them. I believe Steve can also order it for you with little delay. Sorry about not being more specific, but this forum is funded and hosted by a kite retailer (Steve/Chico Kites). Providing links to other retailers is generally frowned upon.
2. Krokodil Rokkaku by Carsten Domann/Premier
I believe this one retired was retired when Premier trimmed back the number of Rokkaku kites it was producing.
3. Roller-Kanguru by Carsten Domann/Premier
Pretty sure that this was retired about 2 or 3 years ago. Steve used to stock them and at one point had a clearance sale on them. Kind of a shame as it's nice kite and I love the kangaroo on it.
