Good for you on improving your fitness level! But I would say save your pennies and ride what you got for a while longer. Head over to the weight weenies forum for a reality check of their OCD. It's a sick obsession

Forget a sub-20 bike, or even sub-15. Nobody blinks an eye for that. Try around sub-12, and for that, you'd need to start with a decent frame.
Post pics of your bike when you have a chance.
