It's not necessary to start with an acoustic guitar. In fact, electric guitars are easier and more forgiving.
Can't help you about which guitar to get and from where. I have no experience buying an electric guitar.
Agree with the fact that its easier to play on electric guitar. Thats why it isnt recommended to learn on it as you wont be able to handle the acquistic one later (atleast it would be difficult)
secondly, just saw an add in Others section on PG selling an electric guitar.
