scubajoh44:So, if I wait till 2006 and purchase the CD, I'll be able to get updates online? I will not be a PADI pro untill Feb or March.
PADI have decided from 2006 to supply all certified instructors with CD versions of the instructor manual that can be updated online.
I need it for a few of my DM test and I will be doing my IDC soon also.
For your DM exams, you should probably use one supplied by your LDS with the DM section removed. This section actually has the answers to the exams in it, though if you cheat to pass the DM exams you're only making life harder for yourself on an IDC. Most IDCs only have a basic review of dive theory and it's up to you to make sure that you know all you need to know.
I'd borrow one for your DM, then worry about buying one later. I'd suggest thinking about buying a paper version, then when you get the CD version as a new instructor you can just print off the update sections. I've got both versions and tend to use the paper one more often - I don't like taking my laptop away on dive trips where it can get wet and knocked about.
You can buy either CD or paper online from a number of places, for example:

These guys charge £105, but if you deduct UK VAT that works out as around US$150. Make sure that you get the box marked "educational materials" and you shouldn't have to pay any import taxes.
