I am not a fan. I had the book at one stage and got rid of it.
I like the fact that the arrangements stick pretty closely to standard tuning. I had a look at Mike Lydiat's site that you linked above: a great resource, no doubt, but the tunes are arranged in over a dozen non-standard tunings! The Weiser book is much more practical, if you need a couple of pieces to play at a wedding or other event.
