New Alan Colvin web site

could be he is a true enthusiast and is not out to line his pockets (gasp). besides it is easier (for me anyway)to buy a book to have handy while looking at a car or parts instead of lugging a computer around.at home the computer is ok and i would not want to take a lap top to a swap meet.
