You are correct the problem with the cheap light saws in the chatter you get from the thin tops and the vibrations overall, can leave a rougher cut, however as I mostly just make a lot of sawdust, my saw at 5% of the price of yours makes just as good quality sawdust, in fact I would go as far as to say mine is even better yours, I have become a real expert in making sawdust, measure twice and cut once, that is not for me, I measure twice and end up cutting three times.
