I bought mine mainly for the great Hammond sound and the Roland name. The stereo sound through my Space Station is enough to make you wet your pants.
I must admit, however, OOTB was less than stellar at first, but with some easy tweaking, it came to life. I have taken it on many gigs, band and solo, and it gets better all the time.
If I was just a home player and looked at the two small screens without knowing the purpose, I wouldn't be impressed either. The fact is that there is a definite advantage for me as I am not a spontaneous button pusher. The two screens are interactive, and makes setting up songs much faster. The iPad apps are great for that also.
It has taken a bit of work, but I now have something to be proud of.
