I have the UG, and am reasonably happy with it, but it has some serious drawbacks over the SG.
First and foremost, if you mount it in any way where the cable is semi-permanent, you're stuck. The cable does not disconnect from the UG. Mine is mounted above my mirror and the cable routed under the headliner and down the A-Pillar.
If I were parking at the airport for a week and wanted to remove it and leave it at home, I'd have to pull the pillar cover and remove the entire cable.
Scangauge unplugs so you can take it with you every time you park. That's a BIG drawback on the UG because from the outside of the truck, it looks similar to a GPS.
Buttons are on the back, so you can't flush surface mount it. It has to be elevated above the mounting surface enough to get your fat fingers behind it.
I'm not aware of the features/limitations of the two devices on 1st-Gen, but on 2nd Gen, trans temp and some other readings are not available on the UG, but are on the SG.
Yes, the SG is 3x the price, but IMHO, it is a better unit and worth it.
Some day, I might upgrade mine to an SG and move the UG to my wife's Rav4.
