[EX Q]: Considering how much bad music is out there these days, this was nice to come across. Covers a wide range of topics and moods, musicianship is pretty good. I'd recommend it to just about anyone. My tastes are usually heavier and more progressive - Rush, Dream Theater, Iron Maiden, Queensryche. But I like this disc too.
[EX A]: Positive

[EX Q]: By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!
[EX A]: Negative

[EX Q]: This book really takes me back to my childhood. Seeing the prices, my only wish is that I had kept some of these pristine in the box rather than building, trading and ultimately losing track of them.The emphasis here is on figure, theme and specialty modles rather than the standard cars and military models. Covering the '50's-'70's; Sci-Fi, horror, movie, TV and hot rods are the popular subjects here.For each model there is a color photo of the box and sometimes a built model, manufacturer, date, scale and estimated value boxed or built. There is also a brief history of model manufacturing.There are nearly 1000 models here including my favorites, those wacky cars of George Barris and Ed Roth. This is a great guide for the serious collector or someone who just wants to reminisce about those hours of model building fun.
