Is this Solar System a good deal?

I found most of my stuff off of CL. Bought the wire, fuses and such new from other on line vendors. Like stated above you can do it yourself for around $300 or under. I was also looking at the Zamp set up until I did more research on how to install the items myself. Lots of useful you tube videos showing how easy it is. Just make a drawing too on how you want it all set up.
