I have a 16" craftsman model 21601, not sure how much different it will be than yours but I've used it for the past 5 years. I think it's a great beginner saw. It is much louder than the higher end saws but not ridiculous.
Mine has thumb screws for blade change so no tools required.
I keep 3, 5, 7 and 12 blades on hand. Flat blades I don't really use spirals, just my preference.
Most of them are ultra reverse blades
