I received an English manual from Wersi Music USA when I did my OAS upgrade and it didn't cost me a cent. I believe the English Manual in Europe is slightly different though and I have heard of some dealers selling them.

The cost of the OAS 7 upgrade is dependent upon what version of software you are upgrading from and what your previous hardware setup was. The upgrade is both a hardware (newly programmed SG card) and software upgrade. It cost me around $500 to upgrade from OAS 6 to OAS 7 which was a bargain considering all the new sounds, effects, features, and improvements to the GUI.

Contrary to what many people believe upgrading your OAS instrument isn't ultra expensive and if you are technically savvy, the end user can do the upgrade on their own.
