Yup. I'm asking myself the same questions and feeling the same about AMPIf you can self-build a decent induction annealer for $200, it's surprising that no one has mass manufactured and sold them completed.
I, for one, would like to move away from flame annealing and get an induction model that fits within my budget for an annealer. Right now, the AMP is just too expensive for the number of cases I'd be doing.
