Had korg, ketron,Yamaha,Roland..Thinking about an sd7 as an all in one solution for my needs; wondering about price difference in that and an sd60???

Yet I love sounds on old Tyros 2.. For all the guys that have had t4 and t5, does it still take 7 steps to save the smallest change to a registration (memory-reg#- exit bank- yes-save-ok-yes)??

Easier on psr 970/975?

And of course , can today's motl Yamaha sound as good as yesterdays totl ? Or if not am I better off going with t4/5 for familiarity and to avoid that letdown?
