The total weight and the price both sound a little low. They speak of "heavy gauge" construction, but they never actually tell you what gauge steel they use, as most serious companies do.
A home gym is the best idea in the world for some people, and a waste of time for others. IF you are one for whom it is a good idea, then consider that a barbell, a bench, and a power cage or rack are the 3 basics. They should outlive you, and should be as good as you can possibly afford. Definitely do a good search to see what's out there, don't jump at the first one you see.
I have recommended sorinex.com elsewhere on this forum. Their stuff is a bit much for most individual users, but their racks, benches, etc. at least give you an idea of what is possible, and you can judge how far down from there you want to lift on and pay for.
