Hello, I wanted to post these 2 deals I found on Ebay. After a lot of searching, these are the 2 cheapest complete 400w systems.

The Ipower is about $26.39 cheaper, but I went with the Growace.com version for 3 reasons
1-I like that Growace made a nice video detailing exactly what you'll recieve.
2-After watching YouTube videos of people opening their Ipower package, I noticed that Ipower seems to simply put all thier components in a big box and fill up the empty space with popcorn packing material. Growace (as that dude in the video says) has a more custom made shipping package and I'm sure we have all seen Fed-Ex video.
3-Both MH are rated at 36,000 lumens, but the Ipower HPS is rated at 50,000 lumens (ipowergrowlight.com), where as the Growace HPS is rated at 55,000 lumens.
Are these 3 reasons enough for you to spend an extra $26.39, I don't know, but they were for me. You can also get get either system with just an HPS bulb, but the saveings is minimal. If you don't need/want the cool tube, both sellers offer a range of reflector options. The basic Gull-Wing style shaves about $25 off the price. Hope this is helpful to you.
