Buy the PNT rollaboard...its pricey but you get what you pay for, especially if you are going to be commuting. That thing is a TANK. Avoid TravelPro like the plague; that **** is business traveler/FA luggage and it won't last...
I have the PNT split-top flight case. Its a good bag and fits a TON of stuff, but I almost wish I'd spent the extra $$$ for the nicer PNT bag because the split-top bag is a little tall in the CRJ (rubs CB panel when opening). Scott is the PNT of flight cases. Once again, you get what you pay for.
