the used market is pretty good, and begining of ridding season, so you should get some decent money for your '10.
I had '05 and now "17ES that I bought new out of the crate, there is something satisfactory about buying brand new, and piece of mind you are the first from day one.
Old FJR's were "good", new FJR's are "great" (but not day-and-night difference)
Personally I love the ES, all LED's lights are excellent
(keep in mind they are not owner serviceable)
...6th gear is OK and almost wasn't needed, considering FJR smooth power band, bike will do "ALL the work needed" in and around 4-5000rpm's effortlessly, 6th gear made a small drop in hwy rpm's (yesterday I made a note; 3000rpm's, 6th gear, flat road, 110kph (68mph) ...redline is at 9000rpm's
...cornering lights are underwhelming, they should have been much, much brighter
good luck with your shopping
