Casio Exilim EX-Z750: worth buying?

I’m afraid of purchasing a digital camera that would peform badly, so I actually had difficult time looking for a suitable one. It’s not the matter of price, it’s usability that matters. And camera should be reliable, my all means. Now that EX-Z850 is out, it’s possible to get a refurbished 7-mexapixel “outdated” EX-Z750. So, are there any happy owners here? If yes, would you mind answering a couple of questions: 1. Are YOU satisfied with you choice? 2. Has it delivered the way Casio promised? 3. Are you looking for a new camera? If yes, then why? eBay has plenty of offers in EU zone (means less shipping charges and taxes), but I never owned a digital camera feel a bit nervous about purchasing online.
