I'm planning to purchase a new workstation and have narrowed it down to two Kurzweil products- the PC 4 88, and the K2700. Going by features, the 2700 would be my choice, except for one issue- the weight. At 52 lbs, this would be a bear for me to transport, especially considering that some of my gigs are solo. The PC4, on the other hand, weighs almost half at 28 lobs. I'm wondering what you think about the weight issue. Anyone gigging with heavy keyboards? Hate that the weight factor is going to be the final deciding point in my purchase.
