If you want to give yourself a present that will make you a happier rider, upgrade your kit: better shoes are huge, as are shorts or bibs. Even a nicer jersey or base layer makes a difference in on-bike comfort. Better glasses are good, too. I'm loving my new Pearl Izumi Elite shorts. I'd upgrade my kit long before upgrading my bike. I reckon I've accumulated ~$3000 in kit components and I don't buy top-end gear.
