I have the U1252B if that will help, but don't own or have access to a U1272A. Comparing manuals (detailed spec pages can really help though).
Now for build quality, it's not bad by a long shot (actually quite good). No, it's not IP-67 rated as the U1272A is, but it doesn't need to be either. It can take a hit from a fall off a table (~1m or so), which is all the abuse it should realistically see. Toss it in water, run over it with a car, ..., probably not (too chicken to test any of this).
Features wise, it's definitely aimed more at electronics. The counter function would be nice as you don't have one, but isn't as good as a separate unit (i.e. allow you to use the DMM for other measurements simultaneously), and if you have a use for it, the square wave gen too (better to get a used FG IMHO, as again, it will free up the DMM for other measurements).
Don't be too concerned over battery life (gets way too overblown IMHO), especially for bench use. Say using it for 2hrs per day, you'd be able to get a ~month out of a battery before needing to recharge it (not running the backlight all the time; OLED versions are the models that chew through batteries). At 8hrs per day, ~ 9 days. Worst case, get a couple of decent low self discharge NiMH batteries and a separate charger (8.4V max rechargeable IIRC; stock battery is 7.2V & what times are based on). That way, you can keep at least one fresh battery on the ready should you need to change it (which is quick and easy to do).
Hope this helps.
If you have any specific questions on this meter, just ask, and I'll do my best.
