I also like them and wish Dirt Devil still made machines like that. Out of those the, the Broom Vac is my favorite.... I have the Broom Vac and the Hand Vac. I too have noticed it's almost impossible to find one on Ebay, especially a Broom Vac, though they seem to be more common than the others. The Ultra MVP is missing the Edge Wedge! I do see the regular MVP from time to time in thrift stores.... I always pass on them because I'm not crazy about hard bodied vacs (save the s/p w/t), and they always have broken handle releases, and broken, taped up bag doors and handles.
We had the second one in from the left when I was growing up. The uncle that raised me gave it to my aunt for Christmas one year (rednecks).... she was offended, but I asked for vacuum every year and never got one because they didn't want to encourage me! It was between our Singer System and our maroon soft bagged Eureka Bravo..... after using the Dirt Devil for so long, that Eureka Bravo felt like a top notch machine! I remember we used it to clean the church and the as I was doing the sanctuary, the snooty minister's wife walked in just as the back wheel flew off. She pulled her glasses down, looked over them, and said in a high pitched tone, "Well what do you expect with a name like dirt 'devil'?" I'll never forget that! That was our second one, the first one stopped turning on within a month so we exchanged it (first one had a red switch, second one had a gray one). On the second one, the wheels came off (then it started burning belts), the attachment clips came off, and the hose/floor lever snapped off, poor thing!
Looks like almost a complete collection there minus the can vacs and triangle stick vac. I think I have the little paper that came with those that has the 90's line up on one side and the Royal line up on the other. We got one with ours, and I wanted all the Royals so bad, I just couldn't stand it. I always pictured living in a big mansion and using those to clean it up.... and I wanted them to be alive like the vacuum on Brave Little Toaster. I still want my vacuums to be alive.... I guess they are in a way when the are plugged in

) Didn't Dirt Devil also make one like the soft bagged one on the right side called the Lite, that didn't come with attachments? I remember many some of those came in hunter green or blue or maroon as well.
Now, if anyone ever sees a Cruiser on Ebay, (the more modern, but still rare power drive chrome and blue model), please let me know!
