Hello I live here at Los Angeles, and I need recommendation on first and cheap keyboard. I researched some and there is one that caught my eye which is Yamaha YPG 235 and my price range is not wide. It's my very first keyboard and I would really love to get them around $100 ~ $200, I don't mind if I purchase new or used one. Please recommend, and please let me know what I should look for If I am buying used one. Thank you!
