I used a little one and the zipper kind of broke. I would not get a cheapo. A busted tent 38 days in to flowering would be quite stressful.
You need to vent with a strong fan that makes some noise. So stealth is an issue. I always find that no matter how well constructed a grow room(or tent) is, it is really clear that its a grow tent from the outside. So you may want to consider a room within a room kind of thing.
You could make it out of wood but make it in a way that comes apart. Like nail the walls together separately and then bolt those together. So you can take it apart when you are done. Also you could consider getting used cabinets, when people remodel there kitchen they toss the old cabinets. Get some of those and then toss them when you move, that can work for a veg or clone area with floro's.
Sorry I don't know about those big tents.
Is your landlord cool about you growing? if not I would keep it small and quickly teardownable. My friend got busted because the landlord was investigating a pluming issue and heard some water dripping (his hydro system running) and thought that was the source of the pluming problem. Found the plants, called the cops. Ouch.
