wig help?

[killerweasel.livejournal.com]

Have any of you found a good wig for Sherlock cosplay? Or maybe you know someone who has? I have very long and ginger hair, so that's really not going to work for Sherlock. I'm not going to color it because... just no. So my options are either leave it the way it is and just pull it back in a braid or something (as I do for most of my stuff) or find a wig. I've had doodley squat luck tracking one down so far. The closest thing I've found is the black haired version of this wig, but it doesn't look quite right. I still have to try a couple more costume shops in the area, so maybe I might get lucky.

Any suggestions?
