I had the opportunity to hear & briefly play the Prelude at Winter Namm back in January and was blown away by this entry level budget arranger's classic rich roland sound & more solid build construction than Yamaha's entry level S-series arrangers. I found the D Beam feature especially cool and potentially useful. The 'icing on the cake' is its UNDER $1,000 (US dollars) street price and weighs ONLY 17 lbs ! The Prelude remains near the top of my ultra portable (with built in speakers) take anywhere budget arranger buy list. - Scott
