I recently bought my first guitar and I trying to teach myself how to play. I bought an SG 400 pro and the neck dive drives me crazy. After holding some les pauls they seem to be a better fit for me.

I dont want to drop a bunch of cash and I am looking at Agile 3100 and Harley Benton 550. Are the upgrades worth it in the Agile or is it better to just get the cheaper guitar as a beginner?
