I myself like the
Oberhiem (matrix 12 is probably the one you want if you have more money). I had a matrix 6 for a while, and was able to play around on a 12 at the University back in the day.
I wouldn't ignore the
Juno 60 either. As for affordable synths, it is quite top notch. Juno 6 is pretty hard to find on ebay.
peace,
