John- You used a terrific word that many bypass here- SUFFICIENT. To me, there is always bigger and better. The key is not to overspend beyond what is sufficient for your use and satisfactory to your ears, and to those of your audience. I like motl arrangers for this. Sure it's nice to have all the bells and whistles and by all means go ahead if it suits you and is within your budget. But I believe some of the newer motls are sufficient for most....
