Yes, TMG is legit.
I have an 06 Cyborg - basically a slightly lighter 04 with a different frame and slightly different LPR design. Internally they are identical and they shoot the same, too. I also used to own a Mini, but then I sold it to a friend of mine. The Cyborg is smoother and quieter to shoot, and is also far more reliable. The Mini of course is a lot smaller and a bit lighter, which you may find more comfortable. The Cyborg's regulator is better so it's more consistent over the chronograph. Cleaning the Cyborg is also a lot easier when the time comes (which is only needed once every maybe 10-20 cases really, anything more is excess).
I highly recommend the 04 Cyborg over the Mini, unless you really care that much about the size of the Mini. It is also lighter, but the Cyborg is also deceptively light itself. Search YouTube for my channel, "slghmrZ3R0" (that's the number zero on the end, not an "o"), I have a few videos of my 06 on there.
And on a 70/45, a properly tuned Cyborg should be shooting roughly a case per fill.
