For those of you that are looking for a more affordable option check out amazon or office max. I bought a stebco vinyl case from amazon for 80 bucks and its been pretty good the last year. The bottom is a little worn because I was too tall for my old Samsonite roller aboard, so I was periodically dragging it on the ground. On that note, I just bought the Luggage works roller aboard with the plastic frame and it supports the flight case A TON better.
Office max has a catalog case too that is like 40-50. If you check out the store (just down college ave, less then a mile from your hotel) they have the same one with roller wheels. They can order it online without them. The store clerk offered to pry them off, but I said ahhh no. I bought a cheaper case due to the entire industry going electronic. You don't need something really expensive. I'm guessing they will be obsolete in 5 years anyway.
Hope this helps. Best of luck to all

. Study hard, study in groups, get to know your sim partner, and don't beat yourself up in the sim when things don't go your way. I really believe everyone has a point in the sim where they don't think they will ever get through it. Mine was sim 4 and my partner's was sim 5. After that everything clicked and got better.
