shopping for my tent

hey guys just upgraded the facility and am looking for new fan/filter to go along with it before I set it up. any thing in canada one would recommend me? looking for a 8" filter and fan, best I can come up with is 230 cad for both on growlightscanada.ca. I would rather get something to last, but more importantly be a little quieter as my 4" are loud even with the fan controller turned down.

I've read some reviews on the fusion breath and some GC members are liking it, but wanted to know if there is any better alternative setup that is comparable or cheaper.

and I got a question about my tent I need the power access to be in the middle. how would you make an opening so that I have a exit port for my power cords. previously before I just cut and taped but am wanting something a little more pro looking
