Its technicaly called a dampner, not a balancer. Just like how most guys call engines, motors, lol. Internal combustion engines, electric motors.
Now that we have that straight, you can never go wrong with an ATI for sure, but, since guys are always looking for cheap, the best, low cost dampner, is the Power Bond line from Pioneer. The Summit brand are decent too, and are made by Rimac. The one to avoid, its the Proffessional Products SFI units. They are truly junk.
