If you are looking for a cool promotional product then I can recommend checking out Flashbay and taking a look at their Key Series USB Flash Drives. I have just had some Bronco ones made that we have given to all the guys as a little pre-Christmas present. They are awesome as they neatly fit onto your normal keyring so you will never be wondering where you put your USB stick when you need it.
What I was really impressed with was the level of customer service that Flashbay provided. Anyone who knows me will know that I am a big believer in giving good customer service and get annoyed at how many companies these days forget how important it is.
