I'm very interested in those books you mentioned Dan but Amazon doesn't appear to have them ( http://amazon.com/s/ref=nb_ss_gw/102-3233984-2545708?initialSearch=1&url=search-alias%3Dstripbooks&field-keywords=Grasshopper+o%27reilly&Go.x=0&Go.y=0&Go=Go)??? Where can I find and buy the books you've mentioned? Thanks! :)
