As a guitarist, we try to be adept at both an acoustic and an electric.
Essentially playing an acoustic and an electric involves slight;y different techniques in playing, although there are some that are common to both.
With acoustic guitar, you use more open chords (chords in their first position) and seldom play beyond the 8th fret. You do a lot of rhythm playing as well as fingerpicking. To solo with an acoustic, you need one with a cutaway design that allows you access to higher frets. Acoustic playing is suited to folk, country, blues and unplgged versions of rock songs but not limited to these alone. Sound-wise acoustic guitars covers both bass and treble quite evenly.
An electric guitar, on the other hand, involves a different set of techniques because of its amplication factor. They are made for rhythm or lead playing with an array of pickup combinations for different tonality.
Whichever one you start with, eventually you should learn to play with both because you'll derive greater satisfaction from playing the guitar.
When I started, I was using a 3/4 size made-in-China guitar that costs $25 from those local stationary shops. The strings were killers but I learn my chords from there and develop my finger strength etc. Then, I moved on to a cheap $60 Aria classical guitar. So much easier to play with the nylon strings but it just didn't sound right with the folk, blues and pop songs that I was learning at that time. Finally I graduated to a $125 Ibanez acoustic and never touched my classical ever again for the next 20 years. In between those times, I also switched to electric guitar and bass for variety. I had to adjust to electric guitar playing because there are a lot more playing positions to learn, and solo playing technqiues as well as scales to master. And I am still learning today.
In short, start right away with either the acoustic or electric and let the passion and momentum carry you through. At your budget, there are plenty of choices. Go to a reputable shop and get one that you like. Soon, you'll realise you can't stop at one or two or three or eight or.......
