The cheapest way is order online through the large equipment distributors such as testequipmentdepot.com and tequipment.net and even amazon.com. You'll save a lot of money that way and they usually have everything in stock. That's what I do when i'm down there. They might possibly give you some issues if you are trying to order with an international credit card and shipping it to a hotel though. One solution would be if you have a friend down there you are visiting it might be easier having them order it for you and you just pay them back cash.
