Too bad St. Louis and Northern California are not closer!! I'm selling a "new", never ridden Cannondale Road Warrior with a step-through frame - fast and light - and because it's "3 yrs old" - I can only charge about 2/3 of it's retail price!
Posters above have good advice! Hybrids are "a plenty". Often people buy bikes new - and hybrids are very popular - then they find they don't ride enough and decide to sell on CL. So you can ideally get a "nearly new, hardly used", good quality bike - and with the money you save, you can accessorize! - to your needs and liking - which is the fun part!!
