is wobbling OK? (sober) - Family Woodworking

I really need to get more veritile in my shop. And, I'm over stubbornly refusing to see that I need a dado set for my table saw. (they scare me ) I occasionally do multiple cuts the hack, whack and chisle out the opening but that is not really the best way to go.
So, I'll on the search for a dado set.
I see the wobble types are much less expensive that stacking types.
Are the wobblers just as satisfactory as the stackers or is/are there drawbacks?
