Holiday, I would buy the EM2000, There is a larger selection of tones[around 1100]. They range from very good to excellent..The added features of the EM2000 over the 55 are many, namely a zip drive and ssci port..The 2000 has the same basic features of the G1000...I use a EM2000 in my band[we pack it up with the sound gear] and it is always on the job..For my solo work I use my preferred G1000[also studio work]..Even in todays market the Old Rolands still shine..Fran
