This is a fantastic deal for a high quality trimmer, so I highly recommend buying if you're looking to get into bookbinding. Used this trimmer for my own books that I bind myself and it's easy to use, though this particular model is pretty big so be prepared to lift it. The instructions that came with it were a little vague though, but if you're having trouble setting up you'll be able to find some videos on youtube of this trimmer and some setup instructions. Either way this works great!
