so I guess I'm not the expert, but for me it's all about the colors. I love bold, gorgeous colors on my son and anyone who's got them has my attention! I'm also a sucker for soft. However, I simply cannot spend the amount that these things go for at auction, and I will never score one off HC so I just look at the pictures.
ETA: Oh yeah, and it's kind of silly but I love her business name, makes me want to buy one even more so that when people ask where I got it I have something cool to tell them.
: But I'm probably the only nerd who has ever thought that, or who will admit it at least!
