Comic Book Talk

What do you use to keep track of your collection? I came across the League of Comic Geeks app and that seems pretty good. I've never really cataloged my collection.
I use CLZ with League as a backup. They're both great, but limit the amount of books with free accounts. The League's pro plan is pretty decent for only $19 a year. CLZ, however, is the cream of the crop and $2 a month. If you're a collector waning to know value, there's an add-on subscription as well for that.
