Milwaukee has their tote coming out, or is out. Hits your price point.

They also have a larger one

Having said that, I have a 5.00 bucket, a great 30.00 bucket bag, and a 12.00 seat that fits everything I need. I can see all tools in the outside pockets and can carry larger tools in the inside.
It's also a seat, a parts organizer and a step stool with the additional top.
Fully versatile and efficient.
Client doesnt know or care, to them you're the guy carrying tools they dont care how you're carrying them only that the job gets done.
I also have a tote like the ones described here, brand new in the truck but dont really use it because I have no need.
