Grow tents: suggestions?

I am looking into getting a set of grow tents, one for a veg room and a flower room. I have one 400w MH/HPS for each. I want to be able to have about 2-3 plants in each tent. What size should I get? What price should I expect? What site should I order from? Any and all input appreciated! Thanks.

2x3 or 3x3 prob best for a 400. Should expect the lower priced ones on amazon to be under 100 bucks. Gorilla are priced a lot higher but quality is bar none. Lower end tents work but folks complain about zipper issues and light leaks. Im looking at the milliard brand ones on amazon to start with that fit in a closet space im building out. Anything bigger than 3x3 id suggest going 600 watts. If you can manage heat then the bigger you can go the better for any space really.
