I think the scout is great. We build quite a lot of simple models to be
controlled by the IRRC, it is perfect for this. It is also good for checking
out larger models before the RCX is cranked up. It is biggest draw back is the
it only having two power outputs. But then if it had 3, I'd only want 4. :-)
