Weight is very important to me. Because I DID lift heavy speakers, organs, etc. for years, my back is if bad shape. Also I have an umbilical hernia (like DNJ and several others) that needs to be fixed.
I have three sets of speakers right now. The heaviest are JBL Eon powered 15's and they are only 39 pounds each. I also have the Peavey Escort system that is wonderful for small jobs. The PSR2000 is the lightest keyboard I've ever owned. The PA80 was also light. They CAN be made good and light and the same time. I had a G800, and the PSR9000. They are manageable, but I much prefer the boards that are half the weight.
