Cactus V5's are your answer. I have two sets, so four total, and they have never failed me once. I haven't tested to their full range, but 10m indoors has never been an issue.
The cheapest I've seen is about $50 a set (what I bought them at last year), but you have to shop around, otherwise $65 is about the going rate per pair.
