+1 here, I met Frank Ventresca at this forum. Since his store is about 100 miles away I've made many a trip to test and buy a keyboard(s). I have purchased S900, S910, Tyros 4, Korg Pa800, Korg Pa2xPro and Korg Pa3x, also picked up some accessories as well. If he ever gets out of the musical instrument business it will be a sorry day for me and any of his other customers.
In the 70s I worked for a local Yamaha, Steinway and Hammond Organ dealer in sales. That dealer despite becoming a friend never treated me as well as Frank has.
