You're right, I didn't see a lot in your market. $500 can buy quite a bit used, my advice would be to hold out for something better or less expensive.

The Bianchi is definitely nice and probably worth $500 but if you're just using it for training I feel like you could find something just as good for that purpose for a lot less money, especially if you're ok with something older with downtube shifters. Anything with brifters commands a serious premium.
