Back when I lived in a Beverly Hills mansion, I had a full-size professional clothes steamer in my laundry room (along with some vintage 1950s soap boxes I bought off ebay).  It seemed like a great idea, but rarely got used.  And only someone living in a really big house has room for a standing steamer.  A travel steamer is more practical, not just because you can keep it in the bathroom or bedroom and quickly deploy it to steam out a garment, but you can also travel with it, and have it at the ready to steam out the suitcase wrinkling.  The Jiffy Esteam
is the most powerful hand steamer available, with a 600-watt heating element, a 3-minute warm up time, and 15 minutes of steaming on one fill up.  It uses tap water, and requires no maintenance.  Buy it for $49 with free ground shipping from AllBrands.com.
