Thank you for your replies and suggestions.
My acoustic guitar is an Austin AA-25D

which I purchased at a music store. It has D'Addario EXP 10’s and the store said that they set it up to Martin specs. The associate at the store recommended going with an acoustic steel guitar so that once I had built up my fingers, I could play electric or classical. I could go back and have them check out the action.
I took some lessons for a couple of months from a guitar teacher. He moved too fast for me and I got overloaded, so I dropped the lessons. I did learn the natural scales and I do OK with those. I’m trying to build up my speed and not get my pick on the wrong string but after 15 minutes, I’m getting bored with the scales. With the scales, generally I’m not holding down strings for very long. In the Simple Am and E lesson, you must hold each cord for an 8 count and the first fret is a killer. It doesn’t take long before my index finger is too sore to play.
I’ll try to get over to Guitar Center soon. The closest is 50 minutes from here. Hopefully there, I can try some other options. Looking online, I see that there are some inexpensive classical guitars with good reviews. If I find something better, the trick will be to convince my wife that I need another guitar when I can’t yet play. :-)
