Good luck with that. I used a Rigid chop saw at someone else's shop it it really sucked. I don't know if it was a bad blade or a bad arbor but I suspect the arbor. If that is the case with your saw a better blade won't help unless it is a very thin body blade designed to be tolerant of wanky arbors.
Years ago I had a Ryobi (BT 3000?) table saw. It came with a Freud blade I'd never seen anywhere else. When the blade started to dull I installed a new Forrest WW II blade anticipating a big improvement. Wrong! The saw started vibrating like crazy. Scary.
It turns out that the Freud blade has special cut outs in the body to allow the centrifugal force of the tooth rim to run in a plane even though the center section was being buffeted by a wanky arbor. The stiff heavy body Forrest blade added sufficient leverage to the wanky arbor to shake the whole machine. After that I bought a new "original equipment" Freud blade and treated it nice.
