Depends on the style you want, I assume form the title (but not the body) you're after a belt?
You could get a large battlebelt with molle to hold endless amounts of kit.
You can get duty belts to do more or less the same but in a much much smaller package (less load though).
And more and more we're seeing riggers belts (more made like duty belts) with small amounts of molle on them too.
I myself have a Helikon Security Belt (duty belt), very sturdy, fairly cheap and comes with an inner velcro belt (god send for duty belts).
I hold my pistol holster, 1 pistol Taco, 2 x M4 Fast Mag pouches (single stack beside each other), TRMR Kydex holster, and a Dump pouch.
Fully loaded it has some weight of course, especially with GBBR M4 mags, but it doesn't ride around much, and if seated right (some modification and personally I like zip ties) nothing moves about and it's just enough for CQB style I play.
Again depends on your play style, how much kit you need also.
Do keep in mind a fully loaded battle belt (or even duty) can get in the way of movability if you have a fully loaded (or even just large) Plate Carrier.
I run a JPC with elastic sides (no mags in them also) so I can run anything on my belt with total manoeuvrability.
And as much as one may like their realsteel Crye or die loadout, it's down to what works, what your budget is, and at the end of the day, it's holding a light weight toy mag.
However saying that I like to spend a little on the load bearing items, and then the less load bearing i.e. mag pouches - I cheap out on.
Hope the above helped.
Quick brand for general gear run down bellow for your interest:
TMC - Crye Clone, made VERY well and almost the same as Crye.
Emerson - Chinese clone company, cheap, cheap, works
8Fields - Same as Emerson, but personally I have seen better quality and design from them (I run 8Fields JPC)
FMA - Very cheap chinese brand, low quality, but if the item isn't hitting walls or doing hard work, it'll be fine.
OneTigris - Basically 8Fields with a bumped price.
Condor - Cheap, but you may find a gem among the mud
Viper - Cheap up priced clones, however they do good pouches and less load bearing items.
Nuprol - Viper 2.0 basically.
Warrior Assault Systems - The bridge between Airsoft and Real steel (Cheap for what it is, and it is a monster)
5.11 Tactical - RealSteel hella overpriced
Semapo - RealSteel ish hella overpriced
Crye - RealSteel - High priced (note not overpriced as their kit is another frigging level of good)
Helikon - Can't comment on realsteel or not, but they are solid and fairly cheap
TacticalTailor - lil pricey but GREAT duty belts
