Contax IIa/IIIa service manuals?
Now that I have a IIa needing a little work, and a IIIa needing a LOT, I'm going to have to get a service manual. The options seem to be a choice between a reprint of the factory manual (eBay seller 'neatphoto') and a PDF version on CD (eBay seller 'uscamera'). I'm inclined to go for the CD because it works out much cheaper with postage to the UK. Does anyone know; are both these versions identical and both of decent quality?
I believe I've also seen a non-factory manual from oldtimercameras, though it doesn't seem to be in print. Is it any good?
