I love my Henry!
I imported a Numatic Henry last year, and have been very impressed with it! It had a funky round plug on it that I had to swap with a standard US plug. It's got incredible suction and airflow, and I love the big bags and filter. The hand-cranked cord reel is fun too! It came with a cheapo set of tools, but it also came with a converter, so any fit-all attachemnts work with it. It's very quiet on both speeds, and I imagine it would hold up well in serious use.
I bought a Turbocat Zoom just to use with the Henry, and it works great! Doesn't bog down at all, and lifts the nap beautifully. My non-vacuum friends always notice and mention Henry smiling in the hallway. He's quite a conversation piece!
