Hi there-
The most important considerations in determining whether you will be happy with your outcome are the mechanism of action of the device, and most importantly, the provider doing the service for you.
I think that unfortunately the marketing folks have gotten this turned upside down, and nice people like yourself start to think that it is the particular device that is important, when this is not the case.
Even with the best technology, someone who is not well trained or experienced will not be safe or able to deliver the best outcomes. Conversely, in the right hands, there are many lasers which could give you a great outcome. In my opinion, the best devices currently available for treatment of sun damage are fractional CO2 lasers. This is my opinion because they have very low risk, achieve reliable and significant improvement usually with only one treatment, and the recovery is very short and relatively easy for most people.
There are several different devices that use this technology (the Fraxel Repair, the Dot, The Mixto SX, Active FX and Deep FX) and any of them would be a good option, but only IF the provider offering you the service is fascile with the device in question.
My best advice to you is to find a board certified plastic surgeon or dermatologist with experience treating the problems that are bothering you (ask your friends), and listen to their advice about what works best in their hands. It really is the carpenter, and not his tools (although good tools help), that will result in your satisfaction. I hope that helps you.
