I have an Omron too but I do prefer to take a BP the old way with a stethoscope. and a BP cuff; its far more accurate and useful in assessing how accurate the automatic one is.
I have an Omron X4 Smart, recommended by my doctor. Cost me around £60. It sends readings to an app on my phone, and I can download them and send by email to my GP.
Have you checked out Amazon? They have them for a third of that price - mine was £24.99 - unless you want something able to take extra measurements. Mine does heart rate and can be set for more than one person.
