I've been kinda out of the loop when it comes to recommending any type of lower cost electric, (I play acoustic) but try and find a used one that feels solid to you and plays in tune up and down the neck.
Don't be in a hurry and go to a place where there are several to choose from.
Play a bunch of them, and don't be pulled in by the pretty one (unless it's solid and plays very well).
Eventually, there will be one that will whisper "I'm the one".
Play a progression of G-C-D....over and over again until you hands and fingers hurt...then keep playing.
Learn as many basic chords as you can and how they fit together with other chords in different types of progresssions.
Try to focus on the rhythm of your plucking and strumming hand a little bit more than your fingering hand.
Both are important, but rhythym is (almost) everything. And most of your tone gets developed in your rhythm hand in the way you attack and mute the strings.
Learn songs that you like and practice them relentlessly. Expand your abilities, and try new things no matter how crappy it sounds at first. Keep at it.
Good luck, and have fun, and work through your frustrations.
And HAVE FUN! That's the most important thing.
