eForCity Leather Case for Barnes and Noble Nook Color, Red
I was a little leery of buying something from a seller who (at the time) was unrated, but the price was right so I took a chance.  I am very pleased with this case!  It fits my Nook Color perfectly, protects it from getting battered when it's bouncing around in my bag, and it's a nice, bright red.  I've only had it for a few weeks, but after daily use it's held up quite well.  It does block the speaker, so when I want to watch videos I remove the cover, but I haven't found that to be much of a drawback.
