Chad,
I noticed in the pictures that it is an 8" saw not a 10". I don't know if that will matter to you, I assume you will be using it mostly for various sheet material and won't ever need to run something more than about 2" thick through it. $25 is about cheap enough that if it works at all it is worth it I suppose. That ViceGrip wrench in the picture is replacing a knob, and while the ViceGrip is worth much more than a knob, it does mean that either the saw isn't built too sturdy or it was somehow treated in a manner that broke the knob. The rust on the ViceGrip makes me question how this guys tools are stored or treated too. I have always worked in shops with great big cabinet saws so I don't know how much of a pain it is to run full sheets of material on a saw this size, but as far as compact saws go this one looks like it has a nice sized table. As for the miter gauge, the good ones are usually sold separately, but most saws come with at least a basic one, if you have a dedicated miter saw you would probably be able to make most the cuts that this would with a miter gauge anyway, you can't get a very big piece of wood between the gauge and the blade on a table that size.
I am not sure what I'm saying as far as a recommendation, but those are the things I would consider if I were you. I wouldn't get it but I have access to fancy saws, it wouldn't be a bad choice if it was going to be someone's first and seldom used table saw.
