I didn't find a simple download for Rxtoolkit and regexbuddy doesn't 
have a demo download so I finally tried regex-coach and it works great!.

It has accepted all my regex (not too complex, but not too easy neither) 
and now I can find where the expression does not match easily in just 30 
seconds!

Thanks,
