Salut,
to the U1253B (OLED). I have one since last year and I am quite happy with it. If you need a meter for outdoors or brightly lit environments it may not be the best option. Until now (even in sunlight) I had been able to read the display, but it can get hard.
Great advantages had been when I was crawling under the table to read voltages. The viewing angle on contrast of the OLED is very nice there. Otherwise the OLED is just some nice new tech. fancy stuff.
The battery time was my biggest concern but right now it was fine. I just needed to put in a spare battery once when I was working. Otherwise I recharge the battery in the meter and I am good to go. Spare batteries are always with me..... for security.....
What I really don't like about the meter is the big charger for the Battery (24V->
) which more reminds me of an early Laptop charger because of the size. Also that you have to wait for the meter to be charged (which can take up to three hours) can be annoying.......once again...spare batteries
A nice feature of the Agilent's is the Infrared Port that can be used with an Bluetooth adapter and run with your Android Phone/Tablet or PC. Sometimes it is handy to log the measurements or have a second remote display.
The Fluke's are fine and tough, sure. Agilent Handheld meters are quite new compared to that and so you have to trust that they are "good". A Fluke is known to be good. The 287/289 seems to be a very fine meter and I like the logging with the integrated display. With the Agilent U125x or U127x you still need a Laptop of Android device to view the stored data.
Otherwise there is still the question if you need a Highend Meter or want one
. Best would be to set a Price Limit and go through the specs and some reviews.
