Great thread and build Lucky13!
I am in the Dodge and Squigs camp with wood a wood framed setup.
Dodge, love the bowling ally Benchtop. I have been looking for something local-ish for about a year. No joy.
As other have noted, metal working skills are a great solution. I lack the skills

and tools so this is the current status of my shop build:
I have the 18" deep 44s. The shallower cabinets allowed me to make 'Tool Trundles' behind them in otherwise unused space. You can see the whole build in the link in my signature.
