I'm picky about my pens, and the price is irrelevant: I've had some of my favorite pens be the giveaway ones! I have a beautiful Waterman I got as a gift, and it doesn't get used much at all, because it's on my desk at home. I don't want to lose a pen that cost over a hundred bucks (how stupid a pricetag is that, anyway?!?) so it doesn't really get used!
I haven't seen any new drug company pens in quite some time. I think they've gone the way of the dodo (around here anyway). But you can still get freebies at the job fairs, and trade shows, conferences, etc :)
