I'm looking on PCB website and thought only the sofboxes come fixed with a speedring that can't be detached. Are you saying that they have foldable softboxes and octas that don't come with a speedring.
You specifically said "wanting to attach possible third party modifiers to them".
The PCB foldables already have speedrings...they're plug and play (they collapse down to the diameter of a speedring because of how they fold open and I like them quite a bit).
The Bowens QR can be mounted to a spigot of an umbrella bracket...it's a brass piece w/ a screw on top. So you could use this for any softbox w/ four rods.
However, tmr's mod for using it w/ an octa involves drilling that hole out, so if you want to use an octa and mount the speedring to a lightstand, you'll have to use the OEC one he recommended, but you'll want to leave the octa set up most of the time ;)
