How much should you spend on purchasing a monitor ?
I’ve had this experience with blood pressure equipment too! Two different devices in the discount market and completely different results. I am of the opinion that this must be checked and calibrated regularly. The risks are simply too great. And since today a clock already has mastered pulse measurement is the risk too great …
There is more to calibration than checking your monitor against the one in the doctor’s office. How often is the doctor’s monitor calibrated and readjusted to read accurately? Since we have gotten rid of the mercury manometer in most clinics and hospitals it is very difficult to calibrate a blood pressure machine. You need to have a a setup to pump the cuff up to different pressures, hold the pressure at that point and measure it against a gold standard (a mercury manometer for example). You can’t do this with the automatic BP machines that use a secret algorithm to compute a blood pressure number from the data. If you were able to get an accurate calibration reading you have yet another problem. The automatic machines have no provision for correction outside of the industrial plants where they were produced.

Good luck getting them to even reply to your request, much less, make a recommendation.
Consumer Reports (the non-profit organization) has reviewed bp machines. They publish a monthly magazine (many public libraries have a subscription) and they also have a website. I found a ratings review at consumerreports.org in the health section.
