QUESTION -
I am assuming volume 3 is the DMD pinball book, late 80's to late 90's ??  how does one ever get one of these ? arent these the most popular, so why no more avail ?  even just to borrow one for a week to see what i am missing out on, can i buy one from overseas ? a 2nd hand good one ? 

also, what is in volume 4 and is it worth buying and why ?, thanks in advance,

Caveman

Vol#3 is sold out mate... not a lot you can do about it till the next print.. unless of course you can source a 2nd hand one.

#4 is the "electromechanical years" and has pinball from its early start right through to start of SS games. Lists machines in decades and is packed with photos etc.. its a great book that showcases the best of the decades with write ups on each, valuations etc.. well worth having and probably my favourite of all of the 4 books
