In an online world, training courses like this are about as relevant these days as VHS players.

All of the generalised info that is covered in these courses is readily available at the ends of your fingertips.

Fine for those who work in the industry as their main source of income and want to write it off as a tax deduction though (or generate a bit of extra income on the side ;)).

For everyone else just use google or ask in this forum. Clay's repair guides as one example covers 99.9% plus any troubleshooting problem you think might be unique has been experienced by other machine owners before you.
