I'm used to a broom myself - till very recently. I didn't want to invest on anything costly, in case I don't like it, so went with this one instead - Dirt Devil Red Versa Power Stick - $18 from Target, highly rated at amazon.com too. It doesn't steam clean.
I don't know how this compares with more costly vacuums, but it's definitely a nice upgrade over a broom. Extremely light weight, doesn't suck too strongly that it pulls an area rug, but strong enough to pick up dirt etc from hard floors - though, sometimes you do have to go over dirtier spots several times.
It's not perfect and I don't know about durability, haven't used it long enough. But for that price, completely fine.
PS: It's so lightweight and easy to use, I use it at least 2x/day, after breakfast and dinner, more on weekends - it really is a replacement for a broom, but works better. With a regular vacuum, I probably use it once a week, hate the bulk, heavy etc. Oh, and it's great for staircase too.
