This thread has inspired me. I've cut all my wood to size and am about to assemble a workbench based on this:

I needed some space in the garage to work.
Since I'm on a budget I went with these plans...modified it to be 8 ft long and 24" wide with six legs.
I set my bench height at 37 1/2 inches. Which felt the most comfortable for me to work either standing or sitting on a stool.
I also upgraded to 19/32 OSB and added additional support under the benchtop.
I spent $50 including screws on all the materials, plus I was additionally motivated to rebuild the second battery of my Ryobi tool set.
When I finish I'll post a pic. It's nothing nearly as fancy as what you've made but for my weekend projects and to keep my Garage organized, it's perfect.
Thank you!
