Hi I'll try and answer your question a little more, too.

You may have some limited success with ddump: http://www.geocities.com/ddumpfrontend/

It's quite old, but it makes a fair copy of some discs. Don't expect it to work with the latest and "greatest" copy protections though. If you really can't buy Alcohol, BlindWrite and/or the other one (I forget) remember they EACH have 30-day trial periods...

It looks like DT Pro will have an imaging option, so if you can only register one...
