Best cheap strip soft box?

I am wanting to pick up two strip soft box. Want to do fitness and body scape photography.
What I currently have. A very large Octabox and a medium size
Softbox ( sorry don’t have dimensions on me at the moment) and two Hensel studio strobes


On amazon I see some cheaper softboxes. Everything comes with Bowen’s mounts. I don’t know if those will work on Hensel’s clamp style mount?
I know there are adapters.

I have seen studioPro 14”x61” boxed WITH grid. Seen some phottix ones. So many off brands. What brands have people used? I am a Home photographer who does as hobby and some rare paid gigs here and there. So not a ton of money to spend.

Side question. Was thinking of picking up one softnbox
And some how using my large octobox as other “strip” box. With some sort of scrim over both sides of box making a rectangle down middle.

does not come with a speed ring but Adorama has the glow speed rings to fit. I purchased 2 of the soft boxes and they are really well made and comes with the grid all for 160.00

Cheetahstand has been developing and bringing to market some nice, economical soft boxes. Many are quick setup which, in my view, is a great feature.
