No offense, but unless you have an unusual amount of disposable income AND an unusual amount of interest in dive computers specifically, I think spending the $1500+ on the sol is a waste of money. Your question kind of makes me think that you don't have a great deal of understanding or interest in computers. For typical recreational diving, less is definitely more when it comes to computers. You need depth, dive time, NDL, N2 loading, ascent rate, nitrox use, and not much else. There is absolutely no proven connection between dive computer conservatism and dive safety. IMO, by far the most important things about a computer are that it's reliable and easy to use.
After spending thousands on gear, training, travel, just so I can spend a few hours underwater in the right places, the last thing I want to do while there is play with a complicated computer. If I want to know my heart rate, I'll just take my pulse, or visit a doctor's office. If I want to know my buddy's air, I'll ask.
