Sorry, Donny, but 'if it ain't broke, replace it' seems to be more your mantra...

Perhaps, you might try making yourself a shopping list of the features you MUST have on an arranger. Perhaps you could take a look at whatever arranger you DID have for the longest time as a jumping off place... (was that the 3k?)

Then unless any new arranger has EVERY SINGLE ONE of those 'must have' features, OS aspects, sounds, weight, whatever it is you DO consider important, just don't bother. Sure, it might be fun to tinker around (but you could do that in the store for free!), but if all your basic criteria aren't met, save yourself (and all of us you will ask for basic support) a whole bunch of remorse

All that time spent trying to pound a square peg into a round hole will be MUCH better spent on more long-term rewarding aspects of music...

I guess we all are just curious as to exactly WHAT you are looking for in an arranger... Truth may be, you don't know yourself or you might not have to try so many to find it...
