Query: Hopefully, it's only the refurbs

I had read so many arguments on why refurb quality is as good or better than originals that I decided to roll the dice on this. I had been eying the 880 for a while, but didn't want to spend the $, so when I saw the refurb and its price it was trigger-pullin' time. I've been through 3, and Amazon has said "enough" ... no more replacements - the product has too high of a failure rate. When it works, it's the coolest thing on the planet, but these refurbs have just been quirky. They have repeatedly taken the programming (which is pretty easy and cool) and worked for a while (which is VERY cool), but inevitably, each has failed and had to be reprogrammed at least once in the 2 short months that I've owned them, and 1 just finally flat-out puked and wouldn't do anything (1 had to be returned because of the LCD screen and not quirkiness). I will probably roll the dice on a non-refurb unit because of how great these are when they do what they're supposed to.
