I am going to purchase some equipment and am looking for suggestions…
You should elaborate on the items you wish to have aloft: lights, flags, scrims, etc. Most of my grip gear is Matthews, and it's built to last forever. Compared to everything else photographic, quality grip gear is very affordable. Also nice is when it doesn't fall over and hurt the talent, customers, and family.
I don't own any centuries, preferring to cover the range with small stands like the Reverse (Manfrotto Nano), the Hollywood Beefy Baby, and the larger rollers. With its steel pin, Beefy Baby can take a grip head and small light with ease. Be aware that C-stands are really designed to hold modifiers on a grip arm, and do not have the footprint or weight capacity for big lights and booms.
In a studio, wheeled stands are the cat's meow if floor space permits. This is particular true for a boom: I can move an 80-lb rig with one finger.
