I have used IBDS and they work pretty well but have one draw back. They don't have any type of velcro brake sewn into the bandage to prevent it from completely unrolling during application if it comes out of your hand (and odds are it will..).
North American Rescue or TacMed Solutions offer combination bandages that have these brakes and are a better choice, in my opinion.
I think the best bang for the buck is the Olaes bandage. It has extra gauze and an occlusive dressing included. Whichever you choose, pick one (Having multiple styles of bandages will only complicate matters when time may be of the essence) and purchase it in a couple of sizes. Try to buy a couple of extras so you can practice with them.
