I haven't played or heard one live but I would really hesitate to spend 4K on an arranger for studio stuff. If you were gigging all the time and making good money- yes, I'd think it would worth it. I would also think for studio work you want invest to in software, computer, great mics, and a great workstation. In my oppinion arrangers are for live work, having fun at home, or "stratch pad" to work out ideas in the studio.
