I got to use one of these at a hotel I was staying at recently, and I'm convinced I must get one for my home. I'm just wondering if it is necessary for me to spring for an expensive one or if one of the average or cheaper ones would do just as well. Also, for those who have this at home, I'd like to know what things I'd have to look out for when choosing a model or brand. I imagine that with these types of things that you end up using daily there are bound to be a few pet peeves here and there.
