Great suggestions Don.  I will do as you suggest:  read the options' 
literature and prepare myself for them while still preserving the 
incremental approach as far as possible.  Headers and push on jumpers 
instead of wire jumpers are a sure bet.  Thanks for the other suggestions.
I am sure I will need the group's wisdom to tackle some problem before long.
Thanks,
Raj
