Nearly everything I found on the Kansas City Craigslist has a midcentury feel.
This cute little table for $400.....
...could be used in an amazing room like this
Bamboo chairs (ditch the weird little ottoman, recover the cushions, paint the chairs if you want) - $100
I love this dining table - $800
Really good deal for a wishbone chair - $100
Snatch this one up - $25
These need a couple really cool shades - $65 for the pair
Slap on a coat of vibrant paint (black, orange, green maybe) - $20
Not many people have a need or a spot for a drafting table, but I couldn't pass up this gorgeousness - $200
