I bought this keyboard, which is originally intended for beginners/amateurs, but there is a couple of things that make this an ideal companion for a working musician: it is extremely light, weighting only 3.9 kg, and the dimensions are really nice, fitting in a bag that could be used as backpack (90 x 30 cm is ok, don't buy the 98 cm unless you want it to dance around the softcase). Of course, no hammer action on this one, but the sounds are really nice, particularly the second piano (# 2). Now: two drawbacks: the output is in mini-jack stereo, so make sure you buy the right cable for it. Secondly, you cannot split the keyboard, as I sometimes do when there is no bass player (left part of keyboard with bass sound). Other than that it is a real dream keyboard to bring to rehearsals and small gigs, particularly if you use public transportation.
