I've had an atlas tire changer and for the past several years I was using an atlas balancer - but last summer my balancer's computer went kaput after it got some water spilled on it.
I tried to buy a Katool balancer off Amazon to replace it but it must have been too cheap the order got canceled.
In the meantime I found a used Hunter balancer on craiglist that looked nice. I went and got it.
I have to admit the Hunter is worlds better than my old atlas balancer. It works very quickly and very well. I have no problems with the Atlas tire changer, other than after 10 years I had to replace the air lines because they started leaking.
