Well - assuming you also get a lens and dont have to buy one - its just 50$, so - sure, go for it.
It still will have a MUCH larger sensor than your bridge, thus better image quality, despite the "old" tech. And those old Minolta lenses havent been behind what Canon and Nikon offer, unlike far too many "modern" Sony lenses. And the controls will be worlds ahead of what your bridge offers, too.
Just make sure its a normal zoom, like a 18-55mm or 18-105mm or something like that, or a normal prime, like a 24mm or 35mm or something in that range. And if you get even more lenses than that, even better.
And as goodguy just said - dont make it the entry drug into a bad system. Unfortunately ever since Sony got their hands on the old Minolta system, it went downhill. Its just 50$. Use the camera until you want something better - and then think carefully about what you want to get.
Without a lens, I wouldnt get it.
