Whatever you do, please do not buy a tiny race frame meant for some supple 20 year old and put on a lot of spacers and a flipped stem to make it rideable. We "elderly" need either a frame made for comfort or a traditional roadframe in a size large enough for grownups. That Serotta Fierte is really beautiful but perhaps a tad expensive. If you travel often a Ritchey Break-Away is a nice alternative that would be well inside your budget. (I really like mine set up with 9 speed Campy Racing triple)
