quality 4x8 grow tents help plz

im in the market for a grow tent ill need min 3x6 but all iv seen is 4x8s so ill get one of thos if i need to but i wanted peoples opinion on some quality tents like secret jardin, gorilla tents, ect if ebay ones are good ill get them but i doubt it i need a sterdy one bec itll be holding up 2 heavy hoods a inline fan and ice boxs and im leaning towards gorilla for that quality but there expensive

I bought an ebay 6x6x6 tent a few years ago the quality was decent but nothing i would hang heavy equipment from, i put some hooks in the joist in my ceiling and supported every thing from that...
