I am from the thoughtless School. I started learning guitar with an Electric Guitar with Heavy Distortion into a Marshall kept loud. After playing a while, I then gave a shot at playing Acoustic Guitar. I have had a pretty fast learning experience. So I dont believe in Acoustic to Electric or Electric to Acoustic. Just do what pleases you 'cos that's the thing which will give you more drive to learn more. Go for what you like. I dont get a great drive learning Twinkle Twinkle Little Star and Happy B'Day tunes. I'd rather play the intro riff to Paranoid, Whole Lotta Love and Smoke On The Water.
A crappy guitar is a very bad way to start learning. With a good guitar which is always in tune while practicing, even your ear training happens without your knowledge. You could mistake a fret buzz to improper fretting and vice versa. Which means you will discount your improper fretting and blame it on the fret buzz and keep going. Finally when you play on a good guitar, you might be lagging right from your fretting. I am not saying it will but good guitar is a good place to begin learning. It need not be an expensive one but it should be well playable. I have a Givson with me. It's not great but it's really well playable with no fret buzz or jarre. I suggest at least such an instrument.
