[chbot] Lego Mindstorms Micro Scout

[Mark Beckett]

I asked today about the Micro Scout from our lego expert at work.
He said its around the year 2000, and he thought the original price was 
$200 or so.

The micro scout is rather limited but the link here suggests a few 
options may be possible in P mode.

The newer version Mindstorm have a new controller, but prices are around 
$500 for a kit.

His comment was the prices on Trademe were a bit high, and the prices on 
ebay much better.


Not sure if this helps with the decisions or not.
