Litespeed Tuscany sounds like a nice Ti frameset. I second the others to not worry about resale. Shimano used and new seems to have good bang for the buck. Sad that Campagnolo seems to be going away. I already have a Shimano Ultrgra 9-speed groupset that I would slap on it without a problem. Use whatever you like. If its hilly where you are, then try out a compact crankset (34-50 or something close to that). Sram is also has nice groupsets if you come across them.
