Accurate blood pressure monitor suggestions
I've got an auto inflate model made by Omron, that is very accurate. The reason I know is that I've brought it along to the doctor's office and immediately taken a reading after the doctor or nurse has done so. The numbers are very close with a difference of only two or three points. Their web site is here:

The model I have doesn't seem to be made anymore, but model HEM-780 is probably the closest, although it has more features. The "ComFit" cuff allows you to easily put it on yourself and fits up to a 17" arm. Note, that's 17 inches measured with your arm straight out, not flexed. For larger arms, you may have to go with their professional model, which comes with multiple cuffs, but expect to pay a premium. Unfortunately, the web site doesn't say the size range for the x-large cuff.
Blood Pressure Monitors
I bought mine mail order - don't recall the web site. Just google for Omron blood pressure monitor and you'll find plenty of places that sell them. Also, Costco used to sell an Omron model at a reasonable price, that was slightly different from the models shown on the web site (must have been tailored just for Costco).
The company also provides excellent customer service. If you send a unit to them, they will calibrate it and replace any worn parts. Return costs must be included, which is $5, I believe. The service center is located in the Chicago area, so I was able to bring my unit in and avoid the $5 charge. They calibrated the unit while I waited and replaced the cuff because the velcro was going bad, all at no cost.
Of course, the gold standard is a mercury Baumanometer. They are pricey and you have to know what you are doing to take a measurement. Also, the cuff requires two hands (i.e. another person) to position properly. These can be bought mail order as well. Find a place by googling baumanometer. You'll also need a stethoscope.
