He means the Taylor TTi 2000 digital test kit. It costs a thousand dollars, requires reagents that cost far more than refilling a TF-100, and is more complicated to use than a TF-100. But it is probably accurate and reliable enough to use if anybody is tired of carrying around all those Benjamins in their wallet. Personally I would recommend the TF-100 and donating the remaining $900 to TFP, but to each their own.
