This thread took an interesting turn.
For those interested, here's a couple of links that were very useful to me:

Fraction-Free Methods for Determinants

And (more advanced), very similar concepts but applied to factorization methods:

Roundoff-Error-Free Algorithm for Solving linear systems...

In both cases the full text is available for free to download, just point and click.
