personally i dont see why companies dont sub out parts. If you can find a company that will machine your riser to YOUR specs. Produce them in a fashion that will meet your demands. Then by all means its the smart business choice.
Its certainly not cheap to start a machine shop up due to finding employees, buying the many machines, paying more insurance and workers comp the list goes on.
Im pretty sure your cars, computers, electronics houses werent all built by one company w/o the use of sub contracting.
Sub contracting isnt a dirty word, its letting the company with the specific knowledge and equipment perform the work so the main company can give you the best product available. Im sure Ross would rather spend time on design, product assembly and marketing.
This isnt the govt where the product is made using the lowest bid that was won.

someone needs to take the "button buck" status off andy and angies rank...
