Hey eden,
I will start out by saying I've never played a 314ce, but have the 414ce. I have to agree with scriptor about playing both and seeing which one speaks to you in tone. The play-a-bility of each should be close if properly set-up. The great service you have received in the past would go a long way for me, especially if the sound and cosmetics were close to one another with the two guitars. And, a new guitar carries the warranty. Sometimes it can be a difficult decision. I thought a great deal about a 700, 800,a nd 900 series before I decided on the 814ce. Each were great guitars, it just came down to making a decision of which one and I had input from my wife and daughter.
Enjoy your soon to be new guitar. Sorry I couold give a report on the 314ce.
