Not to put a dampener on anyone's enthusiasm, but if you have to buy a NEW, TOTL arranger to fire up your creative juices (after only one year of ownership of your previous arranger), that can get to be a very expensive habit (unless maybe you get them at cost!).
I STILL have the odd 3am session with my G70, and I've had it for nearly six years, now...!
Make the juices come from YOU rather than the gear, and you can save a boatload of money!
