Actually, if you were very careful and did not mind
the risk, you could implement any X.690 specification
using freeware products that supported pre-1994 ASN.1
versions - but at a cost not so easily seen.
But this would require that you carefully modify the
ASN.1 to create your own version of the standard you
wish to implement. Then you would have to understand
the differences between versions of ASN.1 well enough,
and the capabilities and support provided by the tool
you were using well enough, to design and provide the
supporting code required by the ASN.1 in the actual
standard you were implementing, but missing from your
version of the ASN.1 and supporting freeware tool.
At the back end of your project, you would likely need
far more costly testing before you could be convinced
that you had a reliable product. And maintaining such
code would likely be far more costly and error prone
than what you could produce by simply starting off
with high quality tools. Then there's the time to
market, both with your initial release and subsequent
revisions.
There is no free lunch, only the illusion of one.
