You can also get the Darbee Cobalt for $220 shipped if you want ... but for $10 difference, I'm not sure why you would.
I got one of those in October and it came without a power supply. Contacted both Darbee and Solid signal and they both kept punting the ball back and forth so I gave up and just bought one. Customer service at both those places sucked for me. At least the results were good after all the hassle.
