I think the alloy campy sounds like a good option. I have 8sp Shimano 600 (early 90s) on my road bike and think it looks sufficiently slick, the one issue I have with it is the 130 BCD crankset. I would rather have a compact double to save my knees on the climbs. I would definitely suggest going to a bike shop and trying out any systems that you can and basing it on the feel of the group. I think the SRAM stuff may end up looking fine.
