I want to start playing guitar but I talked to a friend who knows and even plays guitars. He said to buy one at walmart to start which I agreed cheap see if I catch on then buy upgrade from it. But then I talked to my dad and he said there are cheaper ones on eBay but I'm scared on getting one that has problems (since it is ebay) so I was wondering where can I buy a good first guitar around or preferibly below 100$ thanks allot!
