Hi, Keith. Let me thank you publicly for this idea. I have contacted the manufacturer of this device, QCAvionix http://www.qcavionix.com and have purchased the device (not for the BP, though I daresay it would work for that, but for another device I have which requires constant battery power. I've also bought, from Radio shack, a 110 V to 12 V AC to DC converter with a cigarette lighter jack. Therefore, I can plug the battery eliminator into that adaptor, and that adaptor into the wall, and I should have permanent power. You might consider doing this, instead of connecting the battery straight to a transformer. Thanks again.

This solution unmodified is also a great idea for powering the unit while on a road trip, if you can get the front seat that is. So here it is. http://www.mypilotstore.com/MyPilotStore/sep/2707 has a device that will run devices requireing up to 4 double a's from a cigarette lighter. Basically it's 3 straight through "shorting" batteries and one battery that is cabled to some electronics which let you step the voltage up or down between 3 and 12 volts. Alone this is nice for car travel. What my electrical buddies suggested was to purchase a 3V transformer and they would solder up the wired battery for me. Thus I now have a 3 volt battery eliminator. An off the shelf option would be much more preferable, but in the meantime it's worth a discussion topic.
