DTS projects

Hi all, I’m currently learning DTS and wanted to get some practice in package building, so as to better understand the product and packages I’ll encounter in new production environments. If anyone knows a site/source showcasing a wide spectrum of DTS projects, preferably already in production, I’d be grateful for a link. I’ve already tried www.sqldts.com I’m learning from ‘DTS: Step by step’, but that only contains one package whose purpose is largely undescribed, I don’t get the feeling I’m solving a problem, there’s no case history, no scenario and no design plan. All feels pretty dry and abstract, hence unmotivating. Anyway, if anyone knows a good site I’ll be grateful. Cheers
