Very nice riding bikes. I have one now. It might be my favorite bike. I lucked out and got one with all original components but I'd probably go Suntour or Shimano if I were building from a bare frame.
Beware the rear derailler hanger. You might need an adapter washer to get non Huret deraillers to work. You can get one off Ebay for 20 bucks or just make your own with a flat washer and a file. I've got the dimensions somewhere if you want them.
