It seems as if I end up buying bits of brake cable housing now and then, and I think it would make sense not to be paying $1 a foot or whatever the LBS charges. I've found different quantities for different prices, and am wondering which kind to get.
I found 500M for 65 cents a meter--I don't have the cash now, but it is helpful for comparison.
I found 30M of Clark's brand for about 79 cents a meter--I'm inclined to get this.
I found sunlite brand for 73 cents a meter.
And Jagwire, 25' for 18.99, close to for $14.95 (plus $5.00 shipping on ebay). A bit more than $2.00 a meter. Probably the best quality, but I'm not sure whether it's worth it.
