Tri-tronics is the best with Dogtra, Dt systems not far behind. Sportsdog is a good, economical collar. Innotek is known for a poor product but may have improved since Sportsdog bought them out.
I would question if you really need a collar. Hunter use them on their dogs because they have to curb/control natural instincts which are encouraged traits bred over centuries. Sometimes it's needed for safety reasons; guns, trucks, etc.. For house pets, general treat training or positive reinforcement is fine.
