A more expensive saw makes a minor difference in that it is more solid, easier blades changes, etc.
I started with a single speed Delta from a pawn shop, moved to a Hitchai, then a Dewalt and now a Pegas. The first two were purchased solely on price and immediate availability. The last two were a combination of price and reputation.
Each change had something better or easier than the previous. But, was the saw better--or was I getting better?
I did have the Dewalt apart a few times lubing bearings and adjusting the tension rod.
