I bought a Martin D1 s/h for about 500 quid and took the it to the local guru/luthier (no longer with us,sadly) who lowered the action and generally set it up. It's now the acoustic I'll reach for when I fancy a strum/pick and is certainly good enough for my limited playing ability
Whilst the D1 is the plain Jane of the Martin dreadnought range , it sounds great and is good value and would be worth a try at your local emporium if they are still making them.
If the budget is a little more generous a more gifted chum of mine has a couple of guitars made by Jimmy Moon and if you are minded to push the boat out a bit they are seriously good instruments and highly regarded eg
