If you are going to be doing occasional cutting just about any will do. Some real bargains can be found in used saws. I inherited a little 16in Ryobi that is not too bad. Long ago I had a lousy little Dremel that only took pinned blades and was awful to use because of the vibration and noise.
There is not that much difference below $200. I personally wouldn’t bother with the mid-range saws. They are not that much better than the cheap ones. More precisely, the low end saws have gotten a lot nicer. The high end saws are in a different world.
The thing to look for in the lower range is the ability to use both pinned and plain end blades. The pinned are about the same size as a coping saw blade (usually) and are “ok” for for stuff that is not very detailed. There are a lot more options once you get to the plain end blades.
