I just got a tristar (black and silver) with power nozzel in mint condition for $25 and a electrolux Upright discovery 2 for $15 with all accessories, I will post some pics soon.
i never saw a eureka rotomatic come in to my servicecenter with such upgraded integration with the rest of the unit.....i would have never had known such a power nozzle existed......thank you for enlightening me so if i get one i will know to send it to you....if someone just sent the head in for service i would know what it was from....
