Since it is a toss up between money and time on this earth,I opt to just buy the best and be satisfied. Hoowever, there are some who are technically proficient,enjoy digging deep. That is a whole different story.
Looks like to me that you have succeeded with drums beating and colours flying as to the impressive array of arranger keyboards that you have. The only thing to do is to enjoy them really....
And I am sure you are enjoying them , best of luck Bernie !!
