While the Bird 43, and it's variants, is the "gold standard", it's accuracy is +/- 5% of full scale. What makes the Bird 43 popular, I think, is its reliability. The aluminum housing and simple, passive power measurement are major factors in that reliability.
The Daiwa CN-501 series are pretty decent. Make sure you get the right one for the power level and frequency range you're interested in. Approximately $140.
The Diamond SX100, SX200, and SX400 range from $105 to $125 depending on power level and frequency range.
I don't think I'd get too excited about the inexpensive, no-name meters you might find on Amazon, Ebay, Banggood, or Alibaba.
