I had that exact same question about a year ago and got the Sol with my tax refund.
Today, based on what I know about the Sol, which I am very happy with, I would investigate other computers with huge displays and wireless air integration. Those are the features I enjoy most.
There is the Mares Icon HD, which doesn't have AI yet, but there is supposed to be an upgrade program for it this year. I think you send in your unit and a couple hundred clams, and they send you back a new AI model.
There is the Sol. And don't they have a Luna or Terra, something like a Sol but cheaper with support for only 1 transmitter?
Liquivision and Shearwater computers have very good legibility. Not sure about AI. Many "tech" computers don't have it. Around here, Liquivision is beloved for the nice bright screen but I have no idea if it is easy to use.
Sacrifice wireless AI and move to no AI at all or a console and there are a lot of other options. (You don't need AI. No one needs AI; no one needs a computer in the first place though, but computers are a convenience and AI is another level of convenience that I sure like.)
See as many models as you can in person, and check out the manuals. If you aren't a deco diver, most any nitrox-capable computer will work for you, but you need to find one with a display and controls that appeals to you.
If I were shopping again today, I would compare the Sol to the Icon HD. Maybe the Icon would win due to a superior display. Dunno, haven't seen one yet.
