I'm in the same situation ^
because I usually heavily modify my bikes so that they're just right for my use.
My least expensive bike is my fixed gear, a Jamis Sputnik. But with a Brooks Team Pro, different fixed cog and chain, changed handlebar, brake levers, bar tape, stem and pedals, as well as replacement brake calipers, I'm guessing that I have ~$835 +/- into the bike. It rides like a dream, though. So, there's that...

Reason: cog, not chainring
