The tunable loop from Eton, that is mentioned above, does work very well for BC use. They are pretty narrow banded, though, which makes DXing a little difficult. They are somewhat directional, as most loops are, that can be nice for nulling out interference. I frequently use one in my basement shop, where it is quite effective.

An out door wire is hard to beat, but these are a lot more portable and you don't have to worry about lightning protection, on the antenna, anyway.

CC Crain makes (or made) an amplified twin coil ferrite loop that works well for BC use too. It is very directional and sensitive. It does need to be powered, though.
