Avoid purchasing a subpar instrument with poor stability and high action. Instead, seek out something of higher quality. A second-hand Yamaha Pacifica makes for an excellent starting point. It's affordable, reliable, stays in tune, and produces great sound. Personally, I often prefer using mine live over various other high-end guitars in my collection.
While electric guitars can offer greater comfort compared to acoustics, the choice ultimately depends on the genre you're aiming for. A good compromise between the two types would be Ovation's Applause series. These guitars feature a slim electric-style neck, offering both acoustic resonance and comfortable playability.
