You must be talking about AutoVue by Cymmetrix. At more than $2000, it's not "cheap".
I made a quick search and found Delcam Exchange v5.6. It's a translation tool that allows you to open and convert CAD files in many formats, including IGES, Parasolid, STEP, ACIS v17, even Catia V5, Pro/E, NX5 and more.
What's interesting, it's a free download, and free to view files; you pay to convert files on a pay-per-translation basis.
