Richard Hemby at the Online Education Blog has a comprehensive list of cataloging software and ends up giving high honors to GCstar for Linux and Windows. A little tongue-in-cheek, I imagine, he mentions cataloging mini vehicles:
Other collection management software allows management of these items but GCStar has jumped out ahead of competitors because the software allows you to catalog your favorite television shows directly from TVBD channels and allows you to catalog mini vehicles. Cataloging mini vehicles will require some manual efforts but the detailing offered is priceless.
GCstar is a fantastic bit of software. In my opinion, one of its biggest strengths is the sheer number of websites that it can scrape for info. Tian, the primary GCstar author, even added a feature for using GCstar as a standalone data fetcher. As a result. Tellico can use any of the GCstar data sources directly. The interface is a bit slower, but it works pretty well. I'd like to make Tellico as modular and useful in return, but haven't been able to yet.
Congratulations to GCstar!
