I know you quite possibly ARE a legitimate poster, Ray, but I am starting to have doubts...
Didn't you just ask this exact question on another post? And have so far not come up with anything in the way of important information for us to help you...
The only speakered 61 about $3000 is the Korg PA800 (a hair less, actually) and the Ketron SD-5. Most speakered 61's are more in the $1-2000 range.
In these price ranges, the Yamaha S910 is very popular (or at least, it's predecessor the S900), the Korg PA500 has fans too. You can find some used Roland E80's at well under $3000 (pretty heavy, though), too.
But we really need better info from you to make a recommendation WHICH.
Anybody can type 'Arranger keyboard' into Google and get all this pricing information instantly, but giving a recommendation WHICH is going to need more than '61 keys and speakers'
