Building your own prop replicas from Lost in Space has become more
and more popular over the years especially since the real props are so
expensive and rare these days. Although you would think fans would be
limited to building laser replicas and other less sophisticated props, it is not true.
The focus of amateur prop builders in the past few years seems to be on
full size robot replicas. These replicas can cost anywhere from $5,000
to $35,000 and vary in detail depending on the abilities and resources
made available to the builder. A project like this can take months if not
years to complete. There is talk that a company such as Sharper Image
might be actually mass producing fully built robot replicas in the near future
but a task such as this would make such a replica still cost between
$5,000 and $10,000.
