Yup - I did. But I was also tempted by the new 614ce on the day I made my decision to buy my 816ce. I spent an extra 2/3 hours on the day doing a direct A/B/C with the 614/814 and 816. But like you, I just found the 816 to be unbeatable. I mentioned somewhere else on this forum, my 816ce is not just the finest guitar I've ever owned - it's the finest guitar I've ever played!
Congratulations on yours - you've got a new friend for life there...
