Excellent product and service. I bought a second-hand Casio CPS-60 keyboard which had no manual. Packed full of features which I had no idea how to operate . . .
Google search found this site (and others with the same manual for sale for $8.99!)
I bought the manual and within an hour the download was available. Quality of the scanned images is good - very clear - and the PDF has been created with the pages in the correct order.
I would definitely use this site again.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Correct manual received and of good quality but the contents of the file for the Service Manual for the same monitor is for a 20" TV not the RGB Monitor.
