I have balanced quite a few tires using the Harbor Freight rig. It does seem to take a bit of time to decide that there is no longer a heavy spot. Now I just make a few cursory passes with the balancer and then accept what I get. I have not ever noticed a problem. Then again, I ride a "vibey" 2008 Versys and so perhaps the problem was just conflated with all of the other sources of vibration. Personally, I love riding this bike. My friend rides quite aggressively and has now given up entirely on balancing his tires. I would not take that approach, but I am not sure that balance matters that much - there that should get some comment.
I would recommend riding the bike some before you think that you need a professional to balance your wheels. Why do you think that they know what they are doing any better than you?
