On guitars - it could be worth checking out pawn shops and the like, so you can see and play what you are thinking of buying. I've also purchased a lot through ebay, but you may need to do a little tweaking to get a guitar set up right. If you're comfortable having a try, ebay could work for you.
I started playing when I was 8 as well, so hopefully your son is beginning on the same very rewarding road. Hopefully you can teach each other a few things too. Happy you found this place man - feel free to ask us any questions as you go, and we'll do our best to answer them...
