Unless you want to spend a bunch of money on a dopp kit, there are cheaper alternatives that will be just as nice and work just as well.
Wilson's leather has a nice kit on for $30, and there are lots of other options that I think are nicer for this price.
I have several dopp kits - the one I use the most is a soft-sided zip top with a compartment underneath - its got a big main compartment with a couple of internal side pockets. It provides good protection without being bulky and compresses nicely to fit snugly into my luggage. Oh yeah, its a no-name I picked up for about $15 on sale at a local drug store (its leather to boot!).
When I travel carry-on, I can fit my entire shave kit into a regulation baggie - I use samples and put products into small travel pots.
So, if you want to spend a lot on a fancy dopp kit, go ahead, but any decent dopp kit will do the trick and even an inexpensive one will last ages unless abused.
