She just spent $400 on a frame on impulse, and probably doesn't have much left to buy components.

That's why I say slow down, and move forward mindfully from here on out. Aside from the potential of buying expensive parts on impulse. You also stand a very good chance of buying parts that won't fit if you're not careful. So just take time to consider each part carefully before you buy it. Make sure it will fit with all the other parts you already have. That way you'll have a bike that is perfect wether or not the parts are expensive if they are all good quality, and fit correctly, your bike will work great.

Make sure you buy parts you feel good about, but ignore the fashion police who say you can't ride a Somec with out period Campy components on it. It's your bike no one has to like it but you.
