This is my new idea: http://www.ebay.com/itm/First-88-Keys-P ... 43abfcd9d2 I'm wondering if anyone here has ever tried one of these. I'm thinking I could buy one for myself, bring it to work, and practice when I'm not busy with 'work things'. What do you think? Could I really benefit and progress in my practicing? Or is it a kooky idea?
