I thought I was going to have to replace my diablo, having been unable to find it the last two weeks, and commuting early in the morning once or twice a week. But I got by this week with a serfas 950 and joystick mk-early?.. Then, yesterday after work I found the Diablo under an ottoman, having already checked in between the cushions in the corresponding chair, in spare backpacks, etc. The glutton in me wishes I hadn’t found it until I’d order, received and charged up a new one… 
but the fiscally responsible self is pleased to save the money, even though a new one would cost about half of what I paid 5 years ago.
