I collect a lot of them. I'm finding though that most (if not all) of the new players have the worst chicken scratch autographs. You look at the older stars, and they have great sigs.
I recently picked up an older
Luongo autograph card, not so much because it's rare, but more that it has his full signature compared to his
later cards.
I'm also not a fan of the band-aid stickers they use now. I usually won't bid on cards that have them (which is almost every new set). I can understand their reasoning for using them, but I think the card makers are getting lazy and using them too much.
If you read Beckett Hockey magazine, they always have a section about getting signatures in person (which is impossible for some of us) or through the mail (which I haven't tried yet).
I liked the recent Franchises set, as it added some new Canuck signature cards for the older players and some great jersey cards of some original six players.
