Welcome to RBW robbcayman! Your line of questions is quite understandable. I was only a year ago that i started asking a lot of the same questions...newly married, i too did not want to have a sad ending. spend some time looking over the threads and looking through the archive, it will help a lot.

I did a pretty thorough search and found that the evolution was the right rebreather for my needs. comming up with an objective analysis of which rebreather is the "best" is pretty much impossible. All of them can kill you. Getting solid training, and continuiously sharpening your skills is the way to make it both rewarding and safe. I would recommend seriously considering weather or not you really need a rebreather. If you are pretty happy with the limits of the diving you are doing then don't bother, a pony bottle may just be enough...rebreathers are expensive and time consuming and i believe it carries greater risk factors. If you want to go deeper for longer, go to more remote locations with fewer bottles, take up close and personal macro photography, stay warmer, get less fatigued then perhaps it's for you.

I am quite happy with my choice to go with a rebreather, even though my longest dives at this point are around 90 minutes and not deeper than 130fsw. i love being able to relax and enjoy being able to hang out in the 70 to 90 foot range for practically the whole dive and receive an optimal nitrox mix at every depth. I am happy i chose the evolution, i think the oxygen controlling system and the temp stick have the edge as far as electronics, but i have also come respect each brand for it's pros and cons. Even the vision electronics that comes with the inspiration or evolution rebreathers has had it's share of electronics issues. No matter what rebreather you can go with, you will need to cary an entire redundant traditional Open circuit system with you and i have to say that that is the single biggest draw back for me, a guy who did exclusively no deco one tank excrusions into the wattery world using a sunto cobra (which never got me bent, never had a single glitch over hundreds of dives and was super easy to use).
And having to monitor the balance of 02, Nitrogen and potential for CO2 build up is many degrees more complex than diving open circuit.

Is it more risky than OC? well, i would say yes, but it also depends on how vigalent and disciplined you are or can learn to be. Is it worth it? that depends on what you need from it...a personal question for which you must gain experience and answere yourself. the feild has come a long way and yet has a ways to go before it's truly ready for the recreational market, IMHO. hope that helps.
