I used Excel spreadsheets, too. It proved invaluable as I worked to complete my '62 Topps baseball set. It helped to keep track of the costs (including postage, grading of raw cards, etc.). Now that I may need to sell it, I have at least a reasonable idea of what I'd like to get for it.

As I was putting the set together I also used VCP to keep track of the cards I needed and any auctions that were going for the cards I needed. I tried to start an inventory of what I had but liked the spreadsheets better. At one point I thought about what would happen if VCP disappeared -- I'd lose all that work!

I'm now keeping my Senators/Twins collection in a spreadsheet to track what I have, the cost, etc. Very handy!
