I have the 2hp grizzly hyrbrid. It's a pretty good saw and it will cut 8/4 without too much hesitation. If you have a dull blade it may slow up a bit. Setup and alignment is a process similar on many saws, though the higher caliber saws are more likely to be accurate out of the box. My grizzly wasn't too far off.
I do consider my grizzly a temporary saw. In five or so years I plan to sell it and purchase a saw stop.
Ask yourself about your long term plans. Are you going to buy the saw stop eventually, anyway? If so, consider saving your money and just getting it now.
