The most expensive of the Hoyts include the Ultratec, Protec and Supertec followed by the Razortec, Havoctec, Cybertec...then the Dynatec....followed finally by the Magnatec and MTSport.

If there are any other TEC model Hoyt bows on ebay then they are previous years designs...case in point, the Powertec you mentioned. I believe the last year they were produced was either ' 98 or ' 99.
