"you'd be WAY better off on carpets with a Filter-Queen or Kirby!"
Meh. I own all three of those vacuums, and my Henry is by far my favorite. Henry is way easier to use than both, lighter, quieter, and the huge bags don't lose suction quickly like those horrible FQ cones.
In the US, if you look online, Henrys can be bought for around 300 dollars on Amazon or ebay. I think they're worth it! I love mine! They have a long pliable hose, and you can cover a ton of area before you have to pull the canister around. Henrys come with a great set of attachments, excellent filtration, and I love the long cord and cord reel. I just had to have one years ago, and I never regretted the purchase! A true low-maintenance workhorse.
