I think you're romanticizing the idea of local music shops way too much. I lived in a big city and all we had was sleazy pawn shops and a handful of guitar dealers that operated like sleazy pawn shops. Not only did they not do any special setup work on instruments before you bought them, if you took something back there and asked them to adjust anything, they'd charge you through the nose for it. Plus anyone unfortunate enough to walk in there ignorant of brands and prices would inevitably leave with whatever weird instrument the store was trying to get rid of. Just MY two cents.
