I am a Radian Onwer as well. Although I am afraid that mine has about 25K miles on it. I too had the disturbingly flimsy fuse box. I remeber the first day I opened it up and was astounded that it still worked properly. I replaced mine as well.
So far everything is mostly ok. I think my rear bearings just decided to go and I have a knocking sound from the crank (I think it is the primary drive chain)
