Hi jtinternet,
It’s great to hear that the information here has been helpful and you are certainly looking at some great quality choices regardless of which one you end up deciding 
There is more information about choosing an adjustable bed in post #3 here and the main adjustable bed topic that it links to that can help you choose an adjustable bed based on price vs features comparisons and also includes some retailers that you can use as good sources of information about the features of the adjustable beds they carry and as pricing references as well (in post #6 in the main adjustable bed topic). Of course there are many other sources as well and prices can change on a regular basis so I would also include some internet searching in your research. I would also keep in mind that online advertised prices are often price controlled so make sure you call the stores you are considering to find out their best prices rather than just looking at websites.
I would consider all the major adjustable bed manufacturers to be closely comparable in terms of reliability so I would use price and feature comparisons to choose between them.
I would also give some careful consideration to the type of features that you may find useful over a longer period of time because some of the features they offer may seem very “enticing” when you are shopping but some people may find that they don’t use them as much as they thought they would once the novelty has worn off.
