Oh my gosh. I LOVE, LOVE, LOVE my Rowenta - my model is "advanced" and I have never had one second of trouble with it. The only 2 little drawbacks are it was very expensive - I got it on sale for $100.00, but bought it at BB&B and had a 20% off coupon, so I really got it for a little over $80. The other drawback is you can only use spring water in it, so I buy a case of spring water and just keep it in my closet.
As far as getting really serious wrinkles out of fabric, I always use a product I buy at my local quilt shop called "Mary Ellen's Best Pess". The stuff works like a miracle.
Before the Rowenta and Mary Ellen's just would not iron anything unless I absolutely had to. Now I am even back to ironing my husband's cotton shirts and slacks!!!! He loves it too.
