Nice haul!!!
I wouldn't have been able to leave those at the store, either. I have a Diplomat LX, which is essentially the same as the 2100, that I rescued from beside a dumpster about four years ago. It had not only a generic hose, but the electrified wand and power nozzle. It had basically two issues--the shutoff valve didn't work and somebody had cut off the cord. I lucked up on a cord winder for it very inexpensively, but I just left the valve disconnected. It works great and has been a real workhorse.
