I've had mine from new, probably at least 20 years. I've only had maintenance done on it, but the light switch has given up. It was going to be fairly involved to get it replaced (a 250 trip both ways, and then back to collect it), so I bought a Bendable light to fix to it instead, which I actually prefer as its brighter and adjustable for position. Other than that, it's been a real workhorse and I intend to keep it. (I got a 730E 4 years ago, but I still piece on this one, because I don't have to wait for it to boot up as I do with the 730).
