used guitars that have been vetted and played especially by people here are ok.
Don't go out of your way to deal with kiesel customer service.
Used guitars are actually more likely to have factory issues. There is usually a reason someone is selling a "mint" "hardly played" guitar at a huge loss.
Schecter KM (if you like hardtail) or JL (if you want trem) are best value used guitars by far.. 3pc neck with carbon rods, SS frets, high quality overall for under $800 usually.. can't beat that (unless you find a used Carvin)
A used 1527 with the best case on the market and better quality for $600-700 beats that
