I just found this thread. Wanted to say thanks for the info as I have been playing with a band for 3 years now. On stage I use a Roland KC. And it is really heavy. I am also looking at a lighter replacement. Someone told me to use one of our monitors and just run my keys through it. I'm not sure that it will be sufficient. But I am going to look at the QSC K12sI understand you perfectly. I solved that problem with a powered speaker. There are many brands to choose from. I went with the QSC K12(K10 and K8 also available). It has 2 inputs, and many cool features and its with 1,000W Class D amp, is very light and very powerful and sounds great. You can use it stand up, wedge or with a tripod stand. Will never go back Keyboard amps, ever.
