Thanks for update and analysis of the different Alfano models. Here's what I found out as well - in addition to what you have already stated.
Pro, has only one temp sensor input, one timing and rpm loop. You can select the numbers of magnetic sensors ( three max )....in short, almost all a starting karter can ask for. Best laptime in theory is visible on computer after a download of data...
Pro+, has in addition to the Pro model, one additional temp sensor input and also a speed sensor input. I have not used one but there are more warning lights which I expect will be for temperature. The literature shows also a rpm bar ( similar to Astro ) so maybe that's another feature above the Pro.
Astro, has all of the above ( but with more input points ie. temp & also more magnetic strip numbers ) plus G force sensor input and also a RPM lites above the display window.
I have the Pro for quite a few years and find it user friendly and nicely built. It does suffer from rare glich from time to time.....but perhaps its my unit.
Depending how u look at it, the Alfano being all in ONE unit ( unlike the UniPro, Aim Mychron 3 Gold & 4 with the E-box ) has its advantages of being more compact and less wires/jacks to go wrong.
Not seen a Lapcom in flesh so wun know how it looks like and goes.....for those who has one, please give a review!
By the way, I am stating the OBVIOUS here. Whilst its good to have data from these system - understanding, interpreting the data and translating this to chassis set up, gearing and driver style change is the MOST IMPORTANT of all. If you fail to do this - it's just an expensive ballast on ur kart.....
