Precisely what I was thinking. I just turned 50 and am due for a colonoscopy and have been seriously considering this alternative, especially because it can find polyps on surfaces of the colon of which optical equipment is incapable. Thanks for the specifications.
When my doctor ordered me to have one, I went in half an hour early with a mile long list of questions and demands. I wanted to know what assurance they could give me the same equipment hadn't just been used on an AIDS patient, and wanted to see the equipment, and how it was sterilized. They took me around the corner and into a little room where a pimply-faced kid sat with one of the long tubes in a pan of something green. He didn't look like he knew how to wash himself, let alone something as vital as that thing. Since that was flexible tubing like a hand-held shower water hose, I still felt the flexible bending joints could easily have held bacterial or infection from the guy it was used on before.
Then the "Pay-for-your-own" CT scans came out, I gladly opted for that, and much preferred it! At least there's no AIDS contamination to worry about. Also, you sit and chat with the doctor afterward, know the results instantly (he points out everything right in front of you, plus they also tell you about every other organ that shows in the scan. I got mine on a $499 "special" and felt it was well worth it for the peace of mind, if nothing else.
Also, you're dead right about the Illegals sucking up all our medical resources. We all pay thru the nose so they can waltz in and get taken care of free. THAT nonsense MUST stop! The Canadians already all come down to the US for their medical care. When our system goes broke because of the Illegals, where are we supposed to go?
