Is there a best brand of transfer paper?

[sajilunni]

From another thread I understand that it's best to use the transfer paper for dark colors on almost every color tshirt. Is there a brand of transfer paper that's considered better than other brands? I will be doing over 50 tshirts so I'm considering buying them in bulk somewhere, but if I can't I have Michael's and Hobby Lobby stores close to me. Where do most of you buy the transfer paper to do your tshirts?
