Excellent! I'm very pleased with quality of Sony DCRDVD-101 owner's manual. The manual has 148 pages and covers basicly everything!. Thanks again for great service!

Outstanding and fast service! I received service manual in a moment after order. Thanks to this manual I can use my printer again!

I downloaded this product and looked through it quickly with Adobe Reader v9. It is clean and a good copy. Some scanned pages are not perfectly square, but that is a minor complaint. The document schematics and board diagrams are easy to read, of good contrast. The whole file downloaded quickly. This is a good service! Sony charges about $100 for the printed version of the same manual. It is still available through their print-on-demand pro parts system, but why would you do that?
