Yamaha DGX620

Hi all, just after opinions on this Yamaha. A mate saw it at an op shop and alerted me to it as they had $350 on it. I thought that it could be either a keeper or at least turn it over and make a dollar, as I got it for under 300. Not too sure of it's age, or the true value of it, but it appears to be a nice unit, except for the weight, which is to be expected for such a large instrument. Just asking for opinions regarding the sound quality and if it is passed it's use by date regarding sounds etc. I still have the Korg EK 50, which is still doing the job, but thought the Yamaha could well have some sounds that the Korg misses. Also, I am familiar with the Yamaha operating system.
