I have a large steam press with automatic steam, so I don't need to use a water spray, but since buying my Rowenta steam generator iron, it hasn't seen the light of day. I find the Rowenta much more flexible and it steams through several layers of clothing or sheets with a beautiful finish. I can take or leave the steam press, but would never be without a steam generator iron now.
I know it's all down to personal preferances, but thought I'd just add this into the mix, hope it doesn't confuse you even further.
