It depends on who the seller is. Most of the power sellers are legit, since they're from an actual music store that are simply trying to sell some of their stuff online. However, I wouldn't trust the other bids that are posted as much. Whatever you do, I'd try to get in contact with the seller first (phone call, preferably over email.) Plus, if the guitar isn't shipped insured, you might get your purchase all screwed up. It's really not worth the risk unless you pay a good deal for overnight, insured shipping.
The safest and best thing to do when actually buying any instrument is to try it out yourself. Of course, you can't do that online, so it's all based on faith...kind of a gamble if you ask me.
Instead, you can go to a Mars Music Store or a Guitar Center near you to find a good beginners guitar to start messing with. I'm sure they could cut you a deal on maybe a free case or something to go with your guitar.
Hope this helps some. Just remember, overall, I wouldn't trust buying from ebay unless they're originating from an actual music store. Whatever you do, get in contact via phone with the seller(s) to see if they're honest and legit. Best of luck! 🙂
