While performance and nashbar bibs are Ok, you can really tell a difference when you move up to Castelli, Descente or Assos. I have gone through a few pairs of performance bibs at $60/pair and now I only buy Castelli at $120/pair. The pad is much better and the lycra is much more comfortable and the seams are done really well with multiple panels. So my suggestion is not to scrimp on something you will probably wear more than any of your other clothes.
