I recently built up a CS-057 using mostly spare (** indicates spare) or budget/used parts from eBay, Craigslist, Aliexpress, etc. Though I did kind of splurge on building a custom carbon wheelset.
Total cost is currently $2,334.48 (includes shipping and tax, price will go down when I sell some things I bought bundled together).
Current weight is just under 22lbs with pedals and bottle cage.
