I think the common thread here is to buy a computer with greater capability than you need right now if you plan on going further in diving.
It doesn't make much sense to save a couple of hundred dollars and then have to replace the computer in a year or two when you want to do advanced nitrox, trimix or CCR diving.
I bought a Nitek 3 in the late nineties, it was way more computer than I needed at the time, and I still use it nearly ten years later.
I've also got a VR3 and ended up upgrading that to the CCR/Trimix features.
I recently had a chance to check out the new Liquivision computer and that looks really nice.
