Does anyone out there own or have experience / opinions using the lower end balancers that Dynavibe and Aces offer? I'm looking to only balance props on light singles and twins both fixed pitch and constant speed props. I know with the 4 banger Lycomings, we are never gonna achieve the smoothness of a 6 cylinder. Seems like both companies offer comparable price entry points on their bottom end models. I believe both of these units are single vibe sensor units vs their big brothers which offer 2 sensors for a lot more money. Yes, it's cheaper to rent than own, but who doesn't love an excuse to buy a new tool?
