I like using zistle.com You can click the cards you want, and export as csv if you want to put them in a spreadsheet or other format
I use Beckett- but that zistle idea with exporting a csv file sounds better. May have to try that!
Beckett.com that is
Trading card databasehttp://www.tradingcarddb.com/
cynicalbuddha beat me to it
Thanks all. Tradingcarddb worked out perfect.
I tried Zistle but the process adding cards I owned took too long, imo. I'll check out TCDB too. Don't know why I haven't been there yet.
