Great ideas. Maybe the LUGNET collective is someplace to begin. You can clearly see the marketing behind the pieces in the Star Wars set minifigs. Want Princess Leia or C-3PO?

I suspect that their idea of bulk and ours is very different. They need to grab some mimimum $$$ per purchase to even make it worthwhile answering the phone. I suspect that figure is in the area of $20. So selling individual pieces between $1 - $4 (...) (25 years ago, 7-Sep-00, to lugnet.robotics)

I agree on both points--the bulk and the pneumatics set availability--but this is still progress over a year ago. There were frantic messages posted not long ago that pneumatics might be going away for good ... so it's nice to see them making a (...) (25 years ago, 7-Sep-00, to lugnet.robotics)

The air hoses shipped with the set are long--and can be cut to whatever (and/or quantity) size the user desires. The catalog/image doesn't specify how long they are, though--but the pneumatics I've seen in sets are shipped the same way, and you cut (...) (25 years ago, 7-Sep-00, to lugnet.robotics)
