Hey MS, Apparently, this meter just came out earlier this year. It is the MediSense Precision Xtra, made by Abbott Labs. It sells for $73. However, the ketone test strips are $32 for 8. Really expensive, but accurate and definitive.
Right now I'm in the midst of a TKD experiment. I'm taking blood glucose and urine ketone levels every 30 minutes to see how ketosis is affected by 50 grams of maltodextrin 60 min. before a workout.
