Taylor and Martin are way too over-rated! Entry level taylor 300 series for example is 1800euros and above (new one), thats arround 2000$. And You dont even get full gloss body, just front plus its cheaper wood (sapele vs mahogany). Same is with Martin. D-16 and performing artist series are great but still, you dont have full gloss body and fingerboard is richlite and not real wood. I saw new Gibson J-15 going for 1100euros, thats 1200$ and you get full solid body, full gloss, great build in pickup and its american made with nitrocellulose finish! Than you have J-35, J-29 all not going above 1700euros.. Great guitars, all full gloss!
In my opinion among these tree guitar giants, Martin , Taylor and Gibson, gibson has best prices.
Most under-rated guitar company for me is Alvarez. My father have MD-200c. I played it quite long time and its great guitar! Retail price was around 1300$ at that time, he bought it over ebay for 800$ with great SKB guitar case, mint condition! :)
