I wonder what the efficiency of the final stage of the ProCaster or Rangemaster is? And it would be great if someone was finally able to test the AMT5000 with a 3 meter whip (such as both those other transmitters use – comparing apples to apples).
But let’s get a little real here. There are lots of factors that affect the overall range of a Part 15 AM transmitter, and all of them, no matter how efficient, will get their signal trashed from dusk to dawn. Here just across the border from Seattle, at this time of the year, you get a good AM signal for about 8 hours a day. For the remaining 16 hours, my signal drops from over a mile to 1-2 city blocks (that’s why I moved over to FM, which at least has a relatively consistent signal 24/7, affected a bit by weather).
Unless you’re in this hobby just for the experimentation, I don’t think you can go wrong with any of the higher end transmitters. Get the one with the most/preferred features for your budget. I’d spend the time you can argue which one’s better in programming your station, building your website, getting the word out (if that’s important to you), etc.
[And my personal opinion is: Get an Industry Canada/FCC certified unit. Compliant is nice, but ultimately you’re taking the word of the manufacturer, as very few can actually properly test that out in the real world. And yes, you can still have an illegal installation with a certified transmitter, but if you’re questioned, you start from the basis of looking like you’re at least attempting to be legal). You can get a used Rangemaster for $400-500, not sure about the ProCaster used market, but a new one’s not much more than that. For me, the AMT5000 is interesting, but it’s close to $300, you have to put it together yourself (not my forte) as well as tune it up, and it’s not certified.]
