I got the mini-Santos to replace it's big brother, mostly because I just don't drink more than perhaps 3 cups at a time, and brewing that little in the large one just doesn't work well. I am extremely happy with the ability of this machine to brew 15-20 ounces of coffee (or, of course, as much as 25).
This brewer works so well that it is difficult to fault it. In all fairness, it did take me a while to get a grind that I liked with the larger version, but that same setting ("4" on my Solis Mulino) took to the junior version so well that all I had to do was take it out of the box, plug it in, and brew a near-perfect pot.
Perhaps the best part of using an electric vacpot as opposed to my previously-regular French press (or, presumably, a non-electric vacpot, although I have not used one) is that I can turn it on and let it do its thing whilst I'm running around like crazy trying to get everything done that I need to get done in the morning and still get to class on time.
Aabree did a great job. No sales tax; no shipping charges; no complaints.
