If you are looking for a suitcase style soalr panel, controller, adn wires, I found the best rpice for Z Amp solar at Discount Solar in Quartzsite, AZ.
Discount Solar - Alternate Energy for an Alternative World
They don't do phone or mail orders, so if you are going through town and are interested in solar, stop by.
Unless it's April through September. They are closed in the summer! There isn't enough tourism to stay open, and tourists/snow birds/etc. are where Q AZ makes it's money.
200 watts of panels, controller, wires, and a 115 amp hr Full River AGM battery were under $1K
The energy they capture will be free!
