Entirely suboptimal, granted. Massively reduced ROI for each dollar spent above maybe $2000 per year. But when the maximum extreme end of the spectrum (without going to 0 ROI) is still less than $1000 per month, why is it even a question?
People who make a fraction of what I do spend more than that on their shiny pickup truck with a perpetually empty bed. These are my work tools.
Proper calculation is: cost/ performance ratio. Then buy a second from the list:)
