Stufflestreet, ChrisA CD-ROM with all known vintage set checklists would be a great idea. It would cost little to produce (less than $1), and I'm betting a lot of collectors would be willing to pay $15 or so a pop to get them.
As for the Standard Catalog, I have one that's really old (2nd edition I think). Since all I collect is vintage and I'm not one to keep up with price changes, it's all I need. But I'd but a CD-ROm if for no other reason than the fact that it's smaller than what I have and it'll be more complete.
