just make sure it's something that can handle being checked (that is, thrown as hard as it can be against hard, uneven surfaces, placed upside down, etc). Even if it's carryon size, chances are it'll end up gate checked someday. My last trip to Mexico, I think I got to actually carry on my carryon on 2 of the 5 planes we used. Every other time, it was gate checked. The Porter handled that fine. (My wife was using my old Tommy Bahama carryon, and I think every time that thing gets checked, the handle gets damaged more.)
Basically, if you just buy a standard suitcase and inserts, make sure you have enough padding above, below, and all around to keep things from bouncing/shifting around when the lid is closed)
I'm a big fan of putting lenses in neoprene pouches. Everything except my 60-250 has a neoprene pouch (the 40mmxs usually shares a pouch with my 15mm ltd using the double lens cap from optech; the 60-250 sits in the nylon padded pouch it came with). They sit in those in my bag, in the drawers of the cabinet I use for storing gear that's not in my bag, and sometimes, just clipped to my camera strap or belt if I'm just going out with a couple lenses. It's not going to save them from catastrophic damage, but it keeps them from rubbing against each other and getting scratches, and adds extra protection for a drop.
