I may mention retail prices on certain components, and then mention I purchased it used, not exact price given. I then go into how I built up system over years selling off the old in order to purchase the replacement.
When I think about the resources I've expended in this pursuit it offends my usually frugal nature. I feel like I'm apologizing more than bragging when I mention prices/value of my system. To think of all the billions who live a subsistence existence, I feel so privileged!
