good setup

hi there everyone!
this is my first post,but i've been reading a lot of posts here for the last few months,
heres my situation.
i have almost 3 grand to invest in a grow system.
im gonna be growing indoor.
ive looked up soo many ways to grow indoor. the bloombox. homebox. bc northern lights. superclosets.

my question is, would it be worth buying these grow closets? anyone have experience with them?

any help will be greatly appreciated.
thanks.

Dunno if this helps but I just got a brand new bud box delivered yesterday! i was growing in a cupboard i converted myself. So as of now I don't have a definate answer but It is the bomb compared to my light bleeding home made job I had before and it is supremely cooler than what I had made. Every thing is not in properly yet it's old ducting you see which I have silver waiting to replace it once the cooltube arrives! you can kinda see my bubblegum which is days away from harvest an I got some afghans x3 (2 males me thinks and one female), shitty swiss mix x2 (both male ARGH!!) an baggie seed x2 both female good 'ol baggie seed!
