Brand really does matter, quite a bit, depending on how much quality matters to you. You may pay more for one brand for the same amount of space, but you could get better lasting durability, better menu support, better software support, better warranties, more accessories (either in the package or that you can buy later) and so on and so forth. Do some research on the Internet to see how durable the brand you want is and go to a store where you can try them out and see what you like the feel of.
