hi Walter,

I'm really liking your book, genuinely; again, thanks, its very well done and very helpful--- has what is needed right up front for newbies, and just enough fluff and historical references to make it interesting and fun. I would recommend it to anyone who loves the WP34s (as I do!) and wants a good reference work (paper is good, colors are good, and the ref content is fabulous).

I plan to order a copy for each of my college students as well.

Thanks again!

Cheers,
