Reasoning
Treat each source as a single perspective. From TechRadar we take the USD price with strongest supporting signal (247.99). From Betafpv official site we take the official USD price (189.99). From OscarLiang blog we take 160. We compute a weighted average using confidences as weights: TechRadar 1.00, Betafpv 0.95, OscarLiang 0.90, resulting in about 200.87 USD.
