Are you dead set on OLED?
I realize it's pretty to look at, but there are issues with it, namely lifespan, followed by burn-in (given the fixed symbols/units on a DMM screen).
Wiki articleCnet articleIt's one of the primary the reasons I opted for the Agilent U1252B over the OLED version (battery life is also very poor on the OLED model).
Hope this helps.
BTW, if you are set on OLED screen, and opt for the VC-890, rapidonline has it for a bit less (~10GPB less than Conrad;
here).
And you would be able to swap the case out for the A variant (blue) with an Agilent, assuming you can find one. Orange is easier to find on my messy bench though (have a blue mat on the main bench, so a blue meter = camouflage in my case).
