Congrats! I don't know shit about PRS, whether SE or otherwise, tbh. I think I maybe played a USA for a few minutes whilst trying out an amp or something, and the neck was really weird for me. Which is itself odd, because different neck profiles don't usually even register with me.
The important parts are that you got a great deal (I don't know about PRS but I do know about deals!) and are loving it. Rock on!
