Perry. If you look at other Alabama locations and even other states too, you'll find the same ads. As said, one doesn't have to be too smart to recognize these are scams looking to take your money. And as it is also said, "If it sounds too good to be true, it probably is". It's a shame that people take advantage of things on the Internet and try to steal from honest folks.
That said, I also watch Craiglist some in my search. I placed a "wanted" ad and have a couple of responses, but nothing of interest to me. I have responded to two legitimate ads and have gotten no response. Maybe folks just place the ads and forget about them.
I haven't even considered CAT machines due to the initial cost and maint. cost if needed. Although I'm sure they are a very good machine, they are just too expensive for my personal use. Making a living with one is a lot different scenario.
