I didn't have a budget for an umbrella braket or a light stand, so I made it from "scratch":
A vivitar 285hv is attached to an IKEA lamp stand. The umbrella was found on ebay, I attached another (dismounted) black umbrella to the back to bounce.
I have no idea what this yellow thingy are called. I found them 8 for 1£ at the pound land in York. It's a sort of hard metal cable you can bend with some foam around. You can grip it around whatever comes to your mind.
It's a bit more versatile than simple ball bungees as they still have some rigidity, so for example, you can use them to attach and direct an umbrella.
They are sold to attach things together when doing DIY jobs. If you have any idea of what it can be...
