Hey welcome to our crazy little world here @ js! 😉
The new squier duos are pretty good, lots of people here who have tried them seem to dig 'em. I loved the feel of the one I played tho I did not plug it in so can't speak to its sound. As far as quality of Squiers go, they can be a bit if-y but its more of a hit & miss then a "they are all crap" kind of thing (does that even make sense?)
I'd personally say to try & find a mid 90s fender duo reissue. They are "extra"(?) Short scale, only 22.5 instead of 24 but the quality is there. I have a '96 that I have retro fitted w/ a squier jagmaster neck (24 scale) so that it more like a regular stang. This is a bit of work but worth it.
If you want a trem then you could try & find a Cyclone (both fender & squier made versions) but that could be spendy & they have a bucker & a single. Also look into a used mustang reissue (69or65) on ebay they can be had for a deal if you have the time to wait.
